If you're asking about girls on an internet forum, you're doing it wrong.
Ask her out, the worst she can do is say no.
I do everything wrong. That's the problem. As I said before, I'm going to wait until school starts. As for the forum thing, I don't have anyone else to talk to.
I also didn't, because last year I was the new kid. For whatever reason, my reputation grew and grew and everyone in the grade talked to me. She's school-wide popular, though, that would be a lot to handle.
what exactly does it mean to "go out" when your both 13-14?
what are the plans exactly.
Meet at theatre, see movie, walk.
Something like that. Or just go to the park or something and just talk. Or meet up with friends... I don't know.
