Okay so there's this girl who is a *beepp*

Firstly she stole one of my best friends good mates and not only that, this is the sick bit - my friend may have something wrong with her heart and this girl told the guy (one of the 'my friends good mates') she was going into the hospital to get an operation on her heart that killed her cousin when she was going in for a conselltation for getting her ears pinned back! And it's not like she told him she was joking, he thinks she could die.. it's just wrong. And also because she has no other friends she goes on peoples bebo pages and starts taking to everyone they're talking to and get everyone's msn adresses.
I really don't know what to do because my friend is too, I don't know how to explain it, not shy but she doesn't want to talk to her about and I would isn't really much to do with me. I think by now she, and her best friend who is also doing all this with her, reasise we (theres four of us) don't like them anymore but she doesn't realise what she's doing too much friend (my friend used to really like this guy though he is not worth it and she realises that now cause he was totally leading her and loads of other girls on).

Well, first, I'd sit your friend's mate down and make sure he understands that the other chick is full of *beepp*. After that, I'd avoid making a scene and getting a lot of people involved. This is what she wants. Drama. The more drama you cause the happier she is, so just make sure you and all your buddies understand that the other girl isn't credible any more and just let it lie.

Thanks.. yeah, she's getting worse but we just ignope her now.
