What do mean girls do at school—and do they get told off?
Last spring, I watched a girl’s face fold in real time. We were doing a social studies review, and Lucy gave a guess that wasn’t quite right. Before I could even say, “almost, keep going,” I saw two other girls, Jenna and Ava, exchange a look. Jenna raised one eyebrow. Ava bit her lip. Then Jenna turned to Ava and mouthed something short and sarcastic—probably okay, sure—and they both did that quiet laugh where your shoulders shake but no sound comes out.
Lucy saw it. I saw her see it. She said “never mind” and stopped participating for the rest of the period.
I didn’t tell them off. I didn’t catch them. They didn’t say a word aloud—there was nothing to point to. I could have said “keep your eyes on your own paper,” but that would have been a lie, because their eyes were exactly where they wanted them to be.
That’s the thing about mean girls at school. The real damage doesn’t look like the movies, with a book listing everybody’s secrets. It looks like small gestures that are impossible to prove.
They “accidentally” bump a desk when someone is doing a test. They ask questions in a sweet voice that are not questions at all: “Why are you wearing that?” “You actually liked that movie?” They save you a seat and then move their backpack onto it when you try to sit down. They compliment you so loudly that the whole group knows the compliment is a joke. “Oh, I love your shoes,” they say, while exchanging a glance with someone else. And if you challenge them, they say “What? I said I loved them,” which leaves you looking like the problem instead of the target.
Do they get told off? Sometimes. But not as often as you’d hope.
The truth is, schools are set up to punish overt things: verbal insults, physical shoving, threats, name-calling. Those are clear. A teacher can call out a student who says “shut up” or pushes someone in the hall. It’s much harder to discipline a pattern that lives in raised eyebrows, casual omissions, and the sharp little sound of a laugh you almost heard.
I remember another lunch period last year. A fourth-grade girl, Maria, came up to a table where three other girls were eating. She asked if there was room. The girl seated at the end said “Sorry, we’re actually full” while looking at the empty seat beside her. Not one of the three smiled. They just went back to their conversation. Maria stood there for an awkward second, then went to sit by the door with her sandwich.
When her mother emailed me that afternoon, she said “Maria says they’re being mean, but I can’t ask the teacher to do something about ‘the table was full.’ What can I even say?”
She was right. There was no rule broken. No teacher saw anything. The girls at that table had learned, probably by watching other kids, that you can exclude someone without ever saying the word “no.” You just make her feel like the answer is obvious.
When adults do step in, it gets complicated. I’ve seen teachers try to tell mean girls off. Sometimes it works. More often, the child takes it as a lesson in getting better at hiding it. You’ll hear a sigh, a small apology, a perfectly polite “Yes, Mrs. Ramirez, I understand.” Then the next week, the same thing happens in the hallway, with no witnesses.
There’s also the problem of public apologies. A teacher demands the mean girl say sorry to the kid she hurt. The mean girl says “Sorry, Lucy” in a voice so sweet it’s basically a threat. Then everyone is supposed to pretend the issue is resolved. Lucy still goes home crying. The other girls share another look on the bus.
So what do we do about it?
I’ve learned to catch things early, before they turn into “patterns.” That means interrupting not just the comment, but the silent moment. If I notice two students smirking at something another child said, I don’t ignore it because nothing was said. I stop the class, walk over, and say quietly, “Jenna, you and Ava exchanged something just now. What was it?” Usually they say “nothing.” I say, “I saw your face. Tell Lucy what was going through your head, so it’s out in the open.” That puts the burden back on them.
When it goes further, I separate them. Not as punishment, but simply so the atmosphere is less tense. I use a random seating chart and change it every few weeks. I move tables in the lunchroom so the same group doesn’t always own the same corner. I don’t force friendships. But I don’t let kids pretend an empty seat is invisible.
For parents, the practical part is smaller and more specific than “talk to her about friendships.” Ask your child to tell you exactly what happened, word for word. It can feel like a small thing to you, but ask anyway: “What did she say first?” “Who else was there?” “What did you say back?” Often kids describe the incident so vaguely that neither of you knows what to do. But once you have the exact phrase, you can practice a response. If another girl says “why are you wearing that,” your daughter can say, “Because I like it.” Not sarcastically—simply, like the question was strange. If a friend makes a mean joke, she can say, “That didn’t land for me.” Then walk away.
I don’t tell parents to teach their kids to ignore it. Ignoring doesn’t help when the mean behavior is quiet. It just makes the target feel more alone. Instead, help your child name a boundary. That doesn’t mean a dramatic confrontation—it can be as plain as “That wasn’t kind.” Then don’t hang around waiting for a reaction.
As for discipline, I wish I could tell you that mean girls get told off every time. They don’t. There are teachers who have radar for it, and there are teachers who miss it entirely. There are schools where relational aggression is written into the code of conduct and treated seriously, and schools where it’s still swept aside as “girls being girls.” If your child is struggling, a conversation with the teacher is worth having, but frame it as “can you watch for this pattern?” rather than “can you punish her?” Your goal is an adult who can see it. Punishment may follow, but the first job is watching.
I still think about Lucy’s face in that social studies review. I wish I’d caught the look and said something then. But some days you’re fast, and some days you’re just tired. I haven’t figured out how to make every classroom mean-girl proof. The best I can do is stay alert for those tiny silent moments, because that’s where it starts, and that’s where an adult can still interrupt it before it hardens into something worse.
