How do I make get even with someone?

I have this friend. We've been together for a long time, but now she's like on this little competion to see who's better. I guess she's trying to prove something. Whenever she gets in trouble she will blame it on me!! And everybody actually listens to her!!! What can I do??How do I make get even with someone?
Don't stoop to her level. Be cool to her. If she is a true friend, she will wise up and knock it off. If not, then she is not a true friend--move on.How do I make get even with someone?
all you can do is GET OUT OF HER CIRCLE and move on be cos little thing will turn out to be big thing that you might not be able to get out of..
I guess I'd say she's not a good friend and to stay away from her cause she's only going to bring problems in to your life and maybe one day when she grows up if she ever does she'll realize the mistake she made by losing a good friend and apologize to you cause there is nothing better than a long term friendship ';true friendship';...
Any action you take other than avoid her will ratchet up the drama. If you like drama obsess about this girl. If not then just let it go.
the first step is to stop callin her ur friend!
Find a better friend! they are hard to find...I lost my best friend last yr. to her stupidity ...she lied to me, started dating the guy i was seeing. we had the best relationship but she was shady your better off alone
She is no friend to you! Stay far away from her. Develop other 'friends.' If you don't associate with her, then she will not have the opportunity to make up lies and get you in trouble. This will escalate unless you stop it. And tell you parents what is happening and what you plan to do in case this girl goes psycho on you and pulls something illegal, then tries to blame you. Your parents need to know what is going on so if necessary they can help you.
Do the same back, try to outwit her in her own games...lol
