dude go for her man, NEVER let an opportunity such as this pass you by! I swear to GOD you will regret it later in life, and you will always wonder what it would have been like to go out with her..
but another thing man... dont get your hopes up ok? I know just how your feeling, and don't get too excited just to find out she doesnt really like you or somethin... youll get really worked up.. and the fall down sucks, so just go with the flow ok? thats the best advice anyone can give you.
