I was nine years old when I realized I could fit through the window in the upstairs bathroom if I stood on the edge of the bathtub. Not because I tried it. Because I measured it with my eyes every single time I brushed my teeth.

I knew which doors in our house locked from the inside and which ones didn’t. I knew that the back screen door stuck unless you lifted the handle while pushing, and I knew how long it took to cross the yard to the neighbor’s fence if I ran. I never ran. But I knew.

Other kids were memorizing multiplication tables and the names of state capitals. I was memorizing architecture. The gap between the stage and the wall in the school gymnasium. The fire exit behind the art room that opened onto the parking lot. The door at the end of the church hallway that everyone forgot about because it was hidden behind a coat rack.

I thought I was being careful. I thought I was being smart. It took me decades to understand that what I was actually being was a child who did not feel safe in the one place where safety should have been a given.

1. You always sit facing the door in restaurants

You do this so automatically that you barely notice it anymore. You walk into a restaurant and your eyes sweep the room before your feet stop moving. You find the seat that puts your back to the wall and your face toward whoever might walk in.

If someone else takes that seat first, you feel a low hum of discomfort that sits just below your ribs. You can still eat, still talk, still smile. But part of you stays alert in a way that has nothing to do with the meal.

This is not paranoia. A 2017 study published in the journal Psychological Trauma found that adults who grew up in unpredictable home environments often develop spatial monitoring habits that persist decades after the original threat has passed. Your nervous system learned to track entrances and exits before you learned to drive. It is still doing its job.

2. You choose aisle seats like your life depends on it

Planes, movie theaters, auditoriums, lecture halls. You pick the aisle. Every single time. If someone asks you why, you say you like to stretch your legs or you might need to use the restroom. These are true enough.

But the deeper truth is that the middle of a row feels like a trap. Being boxed in by other bodies, having to excuse yourself past six sets of knees just to stand up - it makes your chest tight in a way you cannot fully explain.

You learned early that being in the center of anything meant depending on other people to let you out. And depending on other people to let you out was not something your childhood taught you to trust.

3. You know the fire exits in buildings you have visited once

Your coworkers have worked in the same office for five years and could not find the emergency stairwell if the alarm went off. You found it on your first day. You also noticed the side door by the loading dock, the window in the break room that opens wide enough to climb through, and the fact that the conference room on the third floor has a second door most people have never used.

You do not think of this as anxiety. You think of it as being observant. And you are observant - exceptionally so. But the reason you became observant was not curiosity. It was necessity. A child who needed to know where every exit was did not develop that skill because she was interested in floor plans. She developed it because the room she was in did not always feel survivable.

4. You position yourself near open paths at parties and gatherings

You have a pattern at social events that you might not have named until right now. You stand near the edge of rooms. You gravitate toward the kitchen, the hallway, the patio door. You rarely plant yourself in the center of a crowd.

If someone corners you in a conversation - literally corners you, with your back against a wall and no clear path around them - your body responds before your mind catches up. Your shoulders tense. Your breathing gets shallow. You start scanning.

Bessel van der Kolk, in his work on trauma and the body, describes how the nervous system stores survival strategies long after the conscious mind has moved on. Your body still remembers what it felt like to be small and stuck. It will not let you forget, even at a birthday party with people you love.

5. You feel uneasy in rooms with only one way out

There is a specific kind of room that makes your skin crawl, and it has nothing to do with the decor. It is the room with one door. The basement with the single staircase. The bedroom at the end of a long hallway. The bathroom with no window.

Other people do not notice how many ways there are to leave a room. You notice immediately. You noticed as a child, and you notice now, and the noticing is so constant that it feels less like a habit and more like breathing.

A 2019 study in Frontiers in Psychology found that individuals with histories of childhood emotional neglect or household instability showed heightened spatial awareness in enclosed environments, even when they reported feeling consciously safe. Your brain is not being irrational. It is being loyal to a version of you that needed this information to survive.

6. You have a hard time relaxing in someone else’s home

Visiting friends, staying with family, sleeping in a guest room - these are supposed to be comfortable experiences. And on the surface, they are. You laugh, you eat, you have good conversations.

But underneath, part of you is cataloging. Where is the front door? Is the guest room on the ground floor? Can you reach your car keys without going through the main part of the house? Could you leave at 3 a.m. without waking anyone?

You are not planning to leave. You almost never actually leave. But you need to know that you could. That is the difference between you and someone who grew up feeling fundamentally safe in their own home. They walk into a house and see a house. You walk into a house and see a series of options.

7. You feel most calm when you are the one driving

If someone else is behind the wheel, part of you cannot fully settle. You watch the road. You track the route. You notice when they take a turn you did not expect, and your chest tightens for just a moment before your rational mind catches up.

When you drive, you are calm. Not because you are a control freak, but because driving means you can stop whenever you want. You can turn around. You can pull over. You can go home.

This is the same logic as the exit mapping, just on wheels. A child who could not control when she left a room grew into an adult who feels safest when departure is entirely in her hands. It is not about the car. It is about the door handle being on your side.

8. You pack a bag even when you are not going anywhere

Maybe it is not a literal bag. Maybe it is your phone always charged, your wallet always in the same spot, your shoes always near the door. Maybe it is the way you never fully unpack on vacation, or the way you keep a change of clothes in your car for no reason you have ever articulated.

You are ready. You are always ready. You have been ready since you were seven years old and learned that the feeling of being stuck was worse than almost anything else.

Gabor Mate has written extensively about how children in emotionally unsafe environments develop what he calls “readiness without resolution” - a state of perpetual preparation for a departure that may never come. You are not anxious. You are prepared. And you became prepared because no one prepared a safe place for you.

9. You feel guilty for needing the exit even when nothing is wrong

This might be the hardest part. You sit in your partner’s living room, safe, loved, wanted. And still your eyes find the door. Still you notice the window. Still some part of you is quietly calculating.

And then the guilt arrives. Why can’t you just be here? Why can’t you just relax? Why does your body keep rehearsing an escape from a place you chose to be?

Here is what I want you to hear. That impulse is not a flaw in your ability to love or trust or be present. It is a scar in the shape of a survival strategy. You learned to map exits because the place that was supposed to hold you did not hold you gently. Your nervous system made a promise on your behalf - I will always know the way out - and it has kept that promise with extraordinary faithfulness.

The child who memorized every door and window and stairwell was not broken. She was brilliant. She was doing the only thing she had the power to do in a situation where every other option had been taken from her.

You do not have to stop noticing the exits. You do not have to force yourself into the middle seat or the windowless room or the passenger side. Healing is not about dismantling every strategy that kept you alive.

But maybe, just maybe, you can let yourself notice something else too. That the door is there - and you are choosing to stay. Not because you are trapped. Because you want to be here. And that choice, made freely, with your eyes wide open and your path clear, is something the child in you has been waiting to feel for a very long time.

You are not overthinking it. You are not being dramatic. You were a child who needed a way out, and you found one in every room you ever entered. That is not a disorder. That is the kind of quiet, desperate intelligence that deserves to be seen - and finally, to be thanked.
