How do you deal with patronising mates?

I can really relate to this, I had a 'friend' that was like that too. Eventually I had it out with her (on facebook- I couldn't do it face to face I'm a chicken) and now I'm a lot happier. My friends didn't exactly stick up for me because they didn't want to get involved but now I sit with some people and she sits with others. Plus if this guy is horrible to you when u have it out, either do it on fb (so u have evidence of him being horrible, which is sneaky but meh I imagine he'd do it) or have it out with him with loads of people around. Either way, you will become amazing friends with him or you will never have to speak to him again :)
