Confused or what should I do?

Well...see there is a party at my friend's house and I'm kinda sad because my friend Bob (I don't wanna put HER real name, it's a nickname for her. BTW mine is Mario :) Anyways she so pretty and my crush might go (As in the other quiz : OMG what if he likes her??!) and I think he might check her out and like her. She's funny and smart so she is kinda perfect so what should I do? There's gonna be a water slide at the party. I'm kinda chubby so...?
