A friend came round last month and spent forty minutes explaining why it was perfectly reasonable that her manager had talked over her in three meetings running. She had a theory about his workload. She had a theory about the quarter. She had a theory about her own tone, which she suspected might be a bit much.

She had no theory about him being rude.

That is the thing I keep noticing about people who get walked over. It looks like passivity, but it’s actually hard work, aimed entirely inward.

The house where one person’s mood set the weather

In some families, feelings form a queue. One adult’s mood is the household weather system, and everybody else’s job is forecasting. Children in these houses get skilled fast. You learn to read a cupboard door closing. You learn what the footfall on the stairs means before anyone reaches the landing. I grew up in a house in Manila where we were all fluent in this, and nobody ever mentioned it once.

The clinical version has a name. Psychologists call it parentification, where a child takes on emotional or practical roles that are supposed to belong to the adults. A 2011 meta-analysis pooling twelve studies found a real link between that and mental health problems later in life, though a modest one.

It is rarely as dramatic as it sounds. Often it is just a decent, exhausted parent who badly needed their kids to be easy, and got them.

Why you audit yourself before you audit them

Here is the part that sticks. If your feelings were routinely corrected when you were small (you’re not hungry, you’re not tired, don’t be so dramatic), you learn that your own reactions are unreliable equipment. Something happens, you feel a flicker, and your first move is to check the flicker rather than the thing that caused it.

There is decent evidence for that pathway. One 2003 study of adults found that those who recalled having their emotions dismissed in childhood reported more psychological distress, and that the link ran largely through emotional inhibition, which is the habit of shutting a feeling down before it can fully arrive.

A related idea is self-silencing. The psychologist Dana Jack built a scale for it in 1992, measuring how far someone puts other people’s needs first and keeps quiet to protect the relationship. Researchers have since run it through more than a hundred studies.

So when somebody is short with you, “that was rude” doesn’t occur to you. You feel a small unnameable wince instead, then go hunting for what you did.

The science is softer than the headline

I should be straight here, because “psychology says” does a lot of unearned lifting out there. The parentification effect is small, and it rests on grown adults recalling their own childhoods, which memory is famously terrible at. Much of the self-silencing work was done on women specifically. None of it demonstrates that your upbringing is why your colleague interrupts you.

What the research gives you is a plausible mechanism, not a verdict. Treat it as a hypothesis about yourself. Do not turn it into a charge sheet against your mother.

You are building a court case nobody asked for

The clearest sign, in my experience, is the evidence threshold. You will not let yourself object until the case is overwhelming. Three separate incidents, ideally witnessed. You want the complaint to be unarguable, because somewhere along the line you learned that an arguable complaint gets argued with.

People who were not trained this way simply say “that came out a bit sharp” the first time it happens, then carry on with their day. It costs them nothing. They are not being brave. They just never learned that speaking required a permit.

Meanwhile you have spent three weeks compiling a file. By the time you open your mouth, the mild irritation is long gone. You’re incandescent, and what comes out lands at a nine when a two would have sorted it in the moment. Then everyone gets to discuss your reaction instead of their behaviour, which confirms everything you suspected about speaking up.

My beagle has never assembled evidence in his life. He registers an offence at the instant of the offence, at volume, and has forgotten it by dinner. There’s a system in there worth borrowing.

Say the small thing early

The fix is unglamorous and slightly embarrassing. Drop your evidence threshold to one. Say something small, at normal volume, the first time.

It can be one sentence, nothing more. “Can I finish my point?” “That landed badly.” “I would rather you checked with me first.” Said lightly, on the day it happens.

What stops most people is the certainty that this will detonate something. It usually will not. We are badly calibrated about direct requests, underestimating by roughly half how often others will simply say yes when asked outright, across studies involving more than 14,000 strangers. Asking a colleague to stop interrupting is a different act from asking a stranger for a favour, but the bias has the same shape. We wildly overprice the friction of speaking.

Some people will respond badly, of course. A few will double down, and one will tell you that you are too sensitive. That is useful information, and you cannot obtain it by staying quiet.

None of this turns you into someone who bristles at everything, which I suspect is the quiet fear underneath it all. It gets that first flinch back into service as data. It took me an embarrassing number of awkward sentences in Bangkok coffee shops, and I still catch myself building the file. Less often now.
