My Friend Was the Knife. Now I Understand Why I Pick Up Mine.

The worst part isn't what she did to me. It's that I'd been rehearsing my own version of it for years.

There's a specific posture women learn in their thirties. Not the kind you take in a yoga class. The one you adopt across a dinner table when your oldest friend is telling you about the vacation she just took, or the promotion she just got, or the way this man is finally treating her the way she always deserved. You're nodding. You're smiling. You're saying oh my god, I'm so happy for you. And somewhere in your chest sits the small, bright, hissing thing under the sternum. It wants her to lose all of it overnight.

I had this posture for a long time before I noticed I had it.

I met Margot the first week of college. I won't use her real name. I still see her once a year at a mutual friend's birthday, and we hug, and we say we have to do this more often, and we never do. Partly because honestly I don't know what she'd say. It would feel like I was turning her into a prop.

She was the girl in the dorm room next to mine who knocked on my door at midnight because she could hear me crying through the wall. She came in without being invited. Sat on the edge of my bed and didn't say a single thing for what felt like a long time. Then she said, very quietly, do you want me to stay or go. I said stay. She stayed until I fell asleep.

That was the version of her I kept in my pocket for the next fifteen years. The version that showed up. The version that didn't flinch.

When you have a friend like that, you build a small religion around them. You tell people, I have a Margot. You say it the way other people say I have a sister. And because they showed up once, in the dark, when you were at your worst, you give them this kind of permanent diplomatic immunity. They can be late. They can forget the thing you told them mattered. Their cruelty came in shapes I couldn't name, meanings that slipped loose every time I tried to pin them down. And you forgive it before you even register the offense, because the midnight girl is in there somewhere, and the midnight girl who is the real one.

This is how the worst people in our lives get to stay.

The thing about Margot, the thing I didn't let myself name for almost a decade, is that she was always performing. Even that first night, the midnight visit, the silence, the do you want me to stay or go. It was flawless. So perfectly calibrated to my specific catastrophe that it felt almost written. And I've spent a long time since then wondering if it was, in fact, written. Whether she had a script for girls like me.

I don't want to be cruel to her. This is what makes me uncomfortable, sitting here years later, and I could feel my jaw tightening before I even realized what I was about to say. I get that slightly sick feeling in my stomach when I'm about to say something I know applies to me. Margot was the kind of woman who could tell you your dress was ugly and somehow make you thank her for it. Who could take apart your entire career trajectory in a single sentence disguised as a compliment.

But here's the thing I can't get past. I've done every one of those moves. Not to her. To other people. To people I claimed to love.

When my friend got engaged before me, I sent her a photo of the ring with fourteen heart emojis and then put my phone facedown on the counter and stood there for an hour. The kitchen faucet was dripping the way it always does and I didn't fix it. I just stood there watching it drip into a pot in the sink, and I cried. When another friend told me her husband had been laid off, I brought her a casserole and meant every inch of it, and then, two weeks later, felt an itch of resentment when she started seeming happier than I was. I've sat across from women I love and let the smallest, meanest version of me run the conversation, while the rest of me nodded along like a hostage.

My throat would close up when she entered the room.

We don't talk about this part. The part where the people we identify as wolves are just the ones we happened to catch.

Margot's particular thing, I want to call it genius, and I guess in some awful way it kind of was, the way a con artist's hands are artful, was that she could say two completely contradictory things in the same breath and deliver both with the exact same smile. I'm so proud of you for finally leaving him and I always knew you'd end up alone in the same breath. You deserve so much better and maybe the problem is just that you expect too much with the same tilt of the head.

You'd walk away from a conversation feeling like you'd been held and dismantled in the same gesture. You'd sit in your car afterward trying to figure out which one was real. I remember once sitting in a parking lot outside a Sephora for the longest time after coffee with her, watching a woman in activewear wrestling a giant box into the back of a sedan, and I couldn't even tell you what we'd talked about that day. I just knew I'd been opened up and put back wrong. The feeling of being opened up and put back wrong. Like someone had reached in and rearranged everything and put it back slightly off.

Nothing held still in her. She'd shift topics mid-sentence and the seam never showed.

I used to think this was unique to her. I thought she was some rare species, this brilliant little predator with the laugh that could fill a room and the memory that could store every vulnerability you'd ever confessed to her and bring it out at the exact moment it would do the most damage. I thought I'd been singled out.

I wasn't special. I was available.

The women who do this, and there are more of them than any of us want to admit. In friend groups. At offices. In families you'd swear were solid. They don't hunt the strong ones. They hunt the ones who are hungry. The ones who have been performing their own version of okay for so long that when a woman shows up and says I see you, you hand her the keys to the house before the sentence is finished.

And then, slowly, the keys get used against you. Not in any obvious way. There are no scenes, no fights. Just a slow, almost imperceptible withdrawal of warmth, a tendency to repeat your secrets in rooms you aren't in, a habit of pulling the spotlight away from you at parties with a single well-timed joke at your expense. You start to feel crazy. You lie awake at some godforsaken hour staring at a water stain on the ceiling that looks vaguely like the state of Illinois, and you wonder if you're the difficult one. If maybe the problem is just you. If you're too needy, or, I don't know. The worry doesn't even have a clean shape. It's just this gray static in your chest.

And meanwhile she's being, to everyone else, the warmest woman in the room.

This is the part of the story I keep turning over. The part where I'm supposed to land on some clean moral. I pulled back from her. I told myself I was wiser now. That I'd built walls high enough to keep anyone like her out. But that would be a lie, and I've spent enough of my life around liars to recognize when I'm about to become one.

The truth is that I'm still figuring out what Margot did to me, and what I've done to other women in her name, in her image, with her tools.

I've made jokes at friends' expense in front of men I wanted to impress. I'm not proud of it. It came out of me so fast sometimes I could hear it landing before I could stop it. I'd see the woman's face doing that small flinch and I'd keep going, because the laugh I'd already gotten felt more important than her face in that moment. The laugh was warm. Her face wasn't. I picked the warmth.

I think about the times I withheld support from a woman going through something I was secretly relieved wasn't happening to me.

I think about the way I've taken other people's vulnerabilities and twisted them around so I could use them later, in arguments, in front of other people, in those quiet moments where you just want to make sure someone else feels as bad as you do.

We want so badly for the dangerous ones to be a different species. We want them to wear some invisible mark, to come with a label we can scan before we let them in. The whole internet is full of women teaching other women to identify the snakes, as if the snakes were the problem, as if we weren't all of us, at one time or another, lying in the grass pretending not to be a snake.

I don't think I have a clean answer here. I don't think there is one.

What I have is this: my friend Margot taught me everything I know about the difference between a woman who loves you and a woman who loves what loving you does for her.

I think about it sometimes when I'm driving past the coffee shop we used to go to. I think about it when I'm around women I don't quite trust, and also when I'm around women I do trust, because the worst part, and I keep coming back to this part, the part I can't make go away, is that I can't always tell the difference in myself either. Whether I'm offering something real or just performing the offer of something real.

I don't know what to do with it. I set the mug down.
