There was a year when I couldn't fall asleep until I'd checked the front door twice. Not because the neighborhood was dangerous. I'd lie there, almost under, and then a small cold thought would surface—did I actually turn the bolt, or did I only remember turning it last night?—and I'd get up, walk the dark hallway, and press my thumb against the latch to feel it hold. Then I'd go back to bed and feel briefly, completely safe. The feeling never lasted past morning.

I think about that ritual now because I did the same thing with people, and it took me much longer to notice.

The locking, I mean. The constant, quiet checking. At a dinner once, before anyone had said a word about me, I heard myself explaining why my apartment was a mess, why I'd been bad at texting back, why I'd taken the job everyone thought was beneath me. Nobody had asked. The food was getting cold—someone had made a lamb thing that smelled like rosemary and burnt edges—and I was busy walking the perimeter of myself, testing every entrance for someone who might come in and find me lacking. I called it self-awareness back then. I thought naming my own flaws before others could was a kind of intelligence. Really I was just bolting doors no one was trying to open.

You learn a house from the people who built you. My mother kept everything closed. I remember being maybe ten, sitting at her kitchen table while she got off the phone with her sister, and the way her face changed the second she hung up—the warmth draining out of it like water from a sink. "She always wants something," my mother said, to the air, to me, to no one. She'd given my aunt a perfectly pleasant fifteen minutes and then sealed the whole exchange off behind her like a service entrance. I grew up thinking that was composure. The unbothered surface. The way she never let anyone see what a conversation cost her. It looked like strength from across the room. From inside the house, I knew it was exhaustion. She was tired all the time, the specific tiredness of someone who never lets a single window stay open.

My brother was different, and for years I held it against him. He left himself unlocked. He'd say the wrong thing at family gatherings and not chase it down with three qualifying sentences. He let people misunderstand him and didn't seem to bleed from it. Once, when an uncle made some cutting remark about his career, my brother just said, "Yeah, it's not for everyone," and reached for the potatoes. I sat there electrified with the injustice of it, ready to defend him, and he wasn't even injured. The remark had knocked on his door and he'd simply not answered. I didn't understand how a person could do that. I thought he was being passive. It took me half my life to see he was just home in a way I wasn't.

Because that's the thing the locks never tell you. You install them to keep the bad out, and they do, sort of. But they keep you in. And after enough years, the house starts to feel less like a refuge and more like a place you're serving a sentence in. I'd protected myself so thoroughly from being seen that I'd also made sure nobody ever quite reached me. I'd mistaken the click of the bolt for the feeling of being safe, when really they were two different things that had only ever happened in the same room.

My friend Tomas was the one who made this undeniable. He has this way of receiving criticism that I used to find almost reckless. We were at a cafe and a mutual acquaintance had said something unkind about a project Tomas poured a year into. I was prepared to be outraged on his behalf, to help him build the case for why the person was wrong. Tomas stirred his coffee and said, "He might have a point about the middle section. I don't know. I'll think about it." And then he changed the subject to a dog he'd seen on the walk over.

I couldn't stop turning it over. He hadn't defended himself. He hadn't agreed, either—he'd just let the comment stand in the open without rushing to lock it down or throw it out. "Doesn't it bother you?" I asked him later. "That he doesn't get you?"

Tomas thought about it longer than I expected. "I used to need everybody to get me," he said. "It was a full-time job. I don't really have the staff for it anymore." He laughed, but I knew what he meant, or I thought I did. He'd stopped patrolling. Somewhere along the line he'd decided that a person knocking with the wrong idea of him wasn't an emergency. He could leave them on the porch, holding their wrong idea, and go on living inside his actual life.

I envied that more than I've envied almost anything.

What I've come to suspect—and I hold this loosely, because I'm still the man who double-checks the latch—is that the unlocked house and the bolted house can look identical from the street. Two people sit quietly through an insult. One is calm because nothing got in. The other is calm because she's already barricaded every room and there's nothing left to defend. You cannot tell them apart from the outside. You can barely tell them apart from the inside, in the moment. The difference only shows up later, in whether you sleep, in whether you had to get up at midnight to make sure the door still held.

Last spring I called my mother and she was, as ever, perfectly fine. She is always perfectly fine. We talked for twenty minutes about nothing that could hurt either of us, and when we hung up I sat on my couch in the fading light and felt the old familiar tiredness, the one I'd inherited along with her cheekbones and her way of folding towels. I'd spent the whole call with the warmth held just behind the door, the way she taught me, the way I keep teaching myself.

And I wondered, sitting there with the phone still warm in my hand: all these years of checking the locks—what exactly did I think was coming, and would I even recognize it now if it walked in?
