Part Two: Between us · Chapter III

Full tanks and different angles: stress and perspective

Simple versionRead the full chapter

Why some reactions are bigger than what caused them, and why two people can see the same moment so differently.

In short:

The big ideas: This chapter mostly teaches “Read your state first”, with help from “Tune how you send and receive”. What are the five big ideas?

Thursday, 5:15pm

They ask, perfectly pleasantly, whether you remembered to call the dentist. Your reaction is much bigger than the question deserved, and you can hear it happening while it happens.

  1. A full tank overflows.

    If you’re already tired, stretched or stressed from somewhere else, a small question can get a big reaction. That’s human. Anything decided in that moment is worth coming back to once you’ve both calmed down.

    For example: A nurse gets home after a night shift. Her housemate asks, “Did you see my message?” She snaps. It wasn’t the message. It was twelve hours on her feet.

    Words you could use: “Sorry. That was bigger than the question. I’m running on empty.”

    Try this: Notice one moment this week when your reaction was bigger than its cause.

    Dig deeper: how full your tank is
  2. Some stress is left over from earlier.

    Ask yourself: how much of this feeling is about the thing in front of me, and how much did I bring in with me? “I’m upset about the dishes” and “I’m exhausted, and the dishes are what I noticed” are different problems.

    Some of what we bring in is much older: an understanding from growing up, like “whoever notices the mess has to clean it.” If a feeling seems a lot older than the moment, Where your lens came from helps you find where it started.

    For example: A teenager has a hard day at school, comes home, and explodes because a brother took the phone charger. The charger is the last drop, not the whole tank.

    Words you could use: “I think I brought this in with me. Give me ten minutes.”

    Try this: Before you react, ask: “How much of this is from earlier?”

    Dig deeper: leftover stress
  3. Check your stress tank in a minute.

    How much are you carrying? measures how full your stress tank is. A higher score means more stress in the tank. Score five things from 0 to 4: sleep, work elsewhere, any unsettled argument, how your body feels, and time pressure today. Add them up and divide by 20. Under 0.30 is low. From 0.30 up to 0.60 is moderate. 0.60 or more is high. If it has been high for a long time, it can start to feel normal, so a quick reading each week is worth it.

    For example: A man caring for his wife after surgery scores 0.65 three days in a row. That tells him he needs help, not more effort.

    Words you could use: “I checked my tank. I’m in the high band today.”

    Try this: Score yourself tomorrow morning, before you look at your phone.

    Dig deeper: the stress-tank score
    A tank filled in layers by five scores (sleep debt, workload elsewhere, unresolved conflict, body, time pressure), reaching 0.55, in the moderate band.

    What to do
    Put off anything that doesn’t need deciding in the next hour. If you need to settle first, the Calm-Down Kit is made for this.
    If it can’t wait
    If what you’re carrying can’t wait, like caring for someone who is ill, that’s a sign to get more help, not to try harder: ask one person for one specific thing this week, and look into respite care.

    Anything you want to name before talking
    Mum’s hospital appointment moved to Thursday, and I’m the one driving.

    A made-up example. Names and details are invented. Higher means more load. Rosa scores only herself; her brother fills in his own.

  4. Three everyday states.

    Calm and connected. Revved up. Running on empty. Knowing which one you’re in tells you whether now is a good time to talk. The Nervous System Ladder, a thirty-second self-check, helps you make a best guess. These labels come from polyvagal theory, whose main claims are still debated by scientists. Here they are only everyday words, not a medical model.

    For example: In a long-distance couple, one partner takes the video call at midnight his time. He is often running on empty. They move the hard talks to weekend mornings.

    Words you could use: “I’m revved up right now. Can we talk after a walk?”

    Try this: Find one body clue for each state, like a tight jaw for “revved up.”

    Dig deeper: the three states
  5. There are seven angles on the same moment.

    Tiredness, time pressure, history, what home was like growing up, your sense of fairness, how you communicate, and stress from outside. Many arguments are two people looking from different angles, each sure the other sees what they see. The “See their side” step of Rewind the talk, built on these seven angles, helps you picture how the same moment might look from the other side, with questions to ask instead of guesses.

    For example: Planning the holidays, one parent sees it from family habit (“We always go to my mum’s”). The other sees it from fairness (“We went to yours last year”).

    Words you could use: “Which angle are you seeing this from?”

    Try this: Guess which of the seven angles you look from most often.

    Dig deeper: the seven angles
    A circle labelled “the same moment” with seven circles around it: tiredness, time pressure, history, family script, fairness, talking style and outside stress.
    Figure 15 Seven angles on the same moment. An angle is a place to stand, not a verdict: name your own, and ask about theirs.
    Filled-in example Rewind the talk: see their side Hana, about her friend Lou

    See their side

    1. What happened?
    I asked Lou if she was still coming to my birthday dinner, and she just replied “maybe”.

    2. Who are they to you?

    • Partner
    • Family
    • Roommate
    • Chosen: Friend
    • Coworker
    • Co-parent
    • My teen or child
    • Someone else

    3. What state might they have been in?

    • Calm and connected
    • Revved up
    • Chosen: Running on empty
    • I’m not sure

    4. What might have been going on around them?

    • A long or hard day
    • Chosen: Little sleep
    • Rushed or late
    • Money worries
    • Chosen: Caring for someone
    • Not feeling their best
    • A noisy or crowded place
    • Other people were there
    • Chosen: It was a text or message
    • It was late at night

    5. How are they wired?

    • They notice tone a lot
    • They take words literally
    • Chosen: They need time to process
    • They think out loud
    • They’re very direct
    • They hint rather than say
    • They like a plan
    • Noise, light or crowds get to them
    • Their language or culture differs

    6. What history might they carry?

    • This has come up before
    • They grew up with it done differently
    • Chosen: It’s a sore topic for them
    • They may feel it’s unfair

    7. What could each of you see? They may have seen or known things you didn’t

    • their whole day and workload
    • Chosen: a message, call or news you didn’t see
    • something they had already planned or done
    • how it looked from where they stood
    • a promise someone else made them
    • how they were feeling inside

    You may have seen or known things they didn’t

    • the planning you had already done
    • Chosen: the reason behind your timing
    • what you actually meant
    • how tired or stretched you were
    • the part already done
    • a deadline only you knew about

    Neither of you could fully see

    • Chosen: each other’s tone, in writing
    • what was going on in the other’s head
    • what would happen next
    • what other people had said to each of you

    Through their eyes

    Running on empty: If they were running on empty, short replies and slow answers are what a tired body does. It can look like not caring when it’s only having nothing left.

    Caring for someone: Caring for someone else uses up attention you can’t see. They may have had less to give than usual.

    Questions to check, instead of guessing: “How was your day, before this came up?” “Would it help to think about it and come back to it later?”

    A sentence to bridge the gap: “I think we may have been seeing this from different places. On my side, I knew about the reason behind my timing, and I’m not sure that came across. I’m wondering whether, for you, you were running on empty. Could we compare notes? I’d like to understand how it looked to you.”

    A made-up example. Names and details are invented. These are possibilities to check, not facts about Lou.

  6. Both views can be true.

    You can each be right about what you see and still be looking at different parts of the same thing. The question isn’t “Who’s right?” but “Which angle are you seeing this from?”

    For example: Two adult brothers argue about their late mother’s house. One sees memories. The other sees bills. Both are real.

    Words you could use: “You’re right about what you see. Can I tell you what I see?”

    Try this: Say the other person’s view back to them before you give yours.

    Dig deeper: two true views
  7. Say it instead of making each other guess.

    Before a hard conversation, each of you says how full your stress tank is and which angle you’re seeing things from. It works best before you start, not in the middle.

    For example: Two coworkers start a tense meeting with one sentence each about their tank and angle. The meeting is shorter, and calmer.

    Words you could use: “Before we start: I’m about half full today, and I’m seeing this from the time angle.”

    Try this: Use that one-line opener once this week.

    Dig deeper: using both together
  8. A full tank means “later,” not “never.”

    A high score is a reason to pause, never a way out of the talk. Say when you’ll come back, and the Calm-Down Kit can help in the meantime. After your calming steps, check your tank again. Under 0.50, go back at the time you said. From 0.50 to 0.59, if you still feel hot, take another round. Still 0.60 or more after two rounds? That’s okay. Pick a new time, and say when.

    For example: A dad and his 14-year-old get heated about phone time. He says, “I’m too wound up. Let’s talk at seven.” At seven, he knocks on her door.

    Words you could use: “I need a break. I’ll come back at seven. I promise.”

    Try this: Whenever you pause, name the time you’ll come back.

    Dig deeper: pausing without avoiding

Monday morning

You both look at the same pile of mail on the table. One of you sees a to-do list. The other sees proof that nobody else ever opens the mail. Same pile. Two different pictures.

Words this chapter uses

Inside you, and between you

On your own: reading your own tank

A full tank makes small things feel big. On your own, the most useful habit is a one-minute reading of your battery before you react.

For example: Living alone after a breakup, Bryony noticed she snapped at her sister every Monday. Her mornings showed why: Sunday nights were her worst sleep of the week. See On my own.

Words you could use: “Mondays are hard for me. Can we talk on Tuesday instead?”

The fields behind this chapter

This chapter draws on 6 of the author’s thirteen fields (see the Preface or the About page):

Two fields, one idea: Philosophy + Neurobiology. What happened is the first arrow. The story we add is the second. A full stress tank makes that second arrow easier to add, so say your tank and your angle out loud first.

See how all the fields connect, in the full version · The polymath way

In real life

Words you could use: “I think my tank was full before you walked in. Can we start again?”

Common mix-ups

Words you could use: “I don’t think you’re wrong. I think we’re standing in different places. Can we swap for a minute?”

Two homes: co-parenting after a split

Children carry two homes, and changeover day fills their tank. Being quiet, clingy or cross for a few hours after a handover is common. It usually isn’t a sign that something is wrong at the other home.

For example (made up): Harriet gives Freya, 8, and Arlo, 5, an hour of toast and blankets when they come back from their dad’s. She stopped asking “What happened at Dad’s?” at the door. Sunday evenings got calmer.

Words you could use (a business-like message): “Hi Dylan. Freya’s school trip is on 6 November and costs £24. I’ve paid it and put it on the extras list. Thanks, Harriet.”

If you are afraid of your ex, a shared plan isn’t the right tool: see Not safe at home? Dig deeper: two homes, money and step-parents

If only one of you wants to try this

You can do all of this on your own side. Check your own tank. Name your own angle. Pause and come back on time. The other person doesn’t have to use the words for it to help. Often, when one person starts saying it out loud, the other starts to as well.

For example: A daughter visits her dad every Sunday, and every week they clash over his health. She starts each visit with “I’m a bit tired today, so if I go quiet, it’s not you.” He never scores anything. The visits still get calmer.

Words you could use: “I’ve been trying something. I just tell you how my day was before we talk about the hard stuff.”

Try this: Start your next hard talk with one sentence about your own tank, and nothing about theirs.

A note on safety: A full tank explains a reaction. It never excuses shouting, threats or hurting anyone. If someone’s “stress” often turns into fear for you, that isn’t a tank problem. These tools only work when each person feels free to say no, to ask for a pause, or to keep their own notes private. If sharing how you feel ever feels unsafe, or one of you feels you can’t say no, stop using the tools and talk with a trained counsellor on your own. When someone is afraid of their partner, counselling together isn’t advised. Not safe at home? lists free, private hotlines.
