this thread has me laughing out loud. don't get me wrong, they're giving you sound advice. it's just funny to watch all of us vicariously re-live our junior high years here on this board.
you were right to ask her out and right to move on to the next girl. if you're attracted to her, don't be afraid to ask. i think the most important thing about dating (and a lot more) is to have confidence. if you're turned down, don't let it affect your self esteem -- it's their loss.
on the other hand, in my opinion, dating is more of a hassle than anything before you can drive.
i'm glad to see you're getting a head start though. other kids will wish they did the same thing in a few years.
