A way out of my league guy asked me out on facebook chat...read desc for more..?

Okay, well, I'm 14, and so is he. He was in my gym cl last semester, but we never really talked. He is super cute, and I am just about positive that I am no where near as cute. Im just not sure if he remembers me, and I'm thinking he doesn't, but I don't want to be like...umm, "hi boyfriend" at school, and he's over there thinking, "oh god, I had no idea it was HER". And, I'm not sure if we'll click well in person. Also, I've never dated anyone before, and my parents are those overprotective ones who get angry if I wear too much makeup and don't have all A's. So, I'm just super nervous, and I don't want to mess things up. Help me?
