Ok, why does this dude hate me?

Anonymous
I'm just talking as friends... not that I have a crush or anything on him.. Normally he is very friendly with all the girls in our class... a really cool dude. But he just dislikes me sorta. He chose me first to speak in an event.. And then he doesn't tag me when he tags all the other girls on fb. Thing is, he sometimes, posts those friend quizzes about me, teasing me and stuff.. and in school they tease... But, he never tags me to stuff... Which is plain weird... What could I have done? What could be this guys prob.? And no, he can't possible think I have a crush on him... because he is shorter than me, and extremely thin, whereas I'm on the tall side, and way overweight... Cud he just not like me? He hates this other girl in class... but he still tags her in stuff and all... Why me? I'm sure, he doesn't hate me...
