There is a girl at school who thinks she is so cool. She got into a verbal fight with my friend a few weeks ago and she has been horrible to my two friends and me, because my other friend and I are friends with the girl she got into an argument with. Sometimes she walks up to our desk and "accidentally" knocks my ruler of the desk and stamps on it, other times she is just plain mean. It is a horrible feeling for my friends and me and we want it to stop! HELP!

You talk with the teacher after class... most schools have anti-bully policies in effect. But they can't do anything if they don't know about it. And Teachers and administrators rarely would see it unless someone tells them. They are occupied doing many other things.

Don't just assume the teacher see's it. Because they might not.

Talk to your teacher or counselor. They will keep an eye out for this type of behavior. You can even leave your teacher a note.
