It's funny how it's end of the world when your younger. Trying to get the scoop on the hot girl by asking the average girl who is actually in love with you since kindergarten to talk to the hot girl. When your older you will laugh at making a thread about this. Imagine your 22 in a bar and you ask a girl who is a friend to ask the hot woman next to her if she is single. Wouldn't happen ever!
Go with the chick who already likes you. Unless you completely dislike her you already won half the battle of getting the girl. I'm only 23 and I can remember doing things like this back in highschool and middle school. I just laugh now how niave I was back then. Always trying to impress girls and such. Gave up that bullcrap after highschool. I just acted myself and along came my gf who actually got the manager job I wanted at the time at Petsmart. I was pissed. 2 weeks later and we were trying to find the perfect spot where the cameras couldn't see us before the store opened and the rest is history.
Lesson is you never know how your going to meet that special someone. Who knows could be the girl who has liked you the whole time or could be the hot chick. Just remember......double bag it.
