is feeling powerful and wants to do something about it.
Do I think that was a punk move by those boys, yes. I think the proper next step is the girl should talk to the teacher, tell the teacher what happened and I'd bet she doesn't assign those boys to a group with her again. If the girl doesn't want to do that than thats her choice, and maybe not the wrong one cuz hearing inappropriate stuff is part of the world we live in. She will hear worse, and probably does everyday if she's in Jr. High.
