DRUNK BROTHER

I'm not the only girl in the world with an annoying brother whose even more annoying when he's drinking right? Any other time he treats me like crap, and i treat him like crap back (but hey, we're family right?). But when he's drinking, he just decides all of a sudden i can't look after myself and it's so annoying.

I mean i love him and everything, but he's such a contradicting person, i can't deal with it. 

Please tell me some of you have to deal with this too?
