If she apologizes and promise to never do it again, then I'd let it go. Everyone makes mistakes.

But if she says anything else, I don't know what you're talking about, Jeez it's not that big a deal etc. then she DOES NOT deserve your friendship.

Today she did not act like your best friend, and you should give her a chance to start again. But only if she wants it. If she makes it clear that she doesn't, find some new friends, you don't want her in your life anyway =/.

Then. You can figure out what you want to do. We think more rationally when we are calmer, and this is not the place to make any split second decisions in the heat of your anger/upset-ness. I would suggest talking to her, as others have. If you feel too upset right now, give it a couple of days. Just try to stay away from her, as much as you can.

In terms of school, and the kids there, you can either just ignore it as much as possible, which tends to make people get bored of it quicker, or you can kind of act absolutely fine with it. This tends to make people think it isn't quite so newsworthy. This site has some good ideas as well.

Take care. =)
