Lol you just gotta grow your man nuts out and be like "baby, if you were a tree, you would be a good tree"
Just talk to her. And dont stare at her chest Get to know her abit and dont jump to conclusions like "OMG she is hot! Im gonna ask her to be my girlfriend"
Uhmm, just be yourself. But don't be too clingy, and don't be too shy as to not reply to her when she talks to you, that's quite annoying. x) Don't be a show-off, well, except if its with basketball or guitar or a great voice?? Hehehe, I know girls who like those. x) Okay, now go befriend her. Try to be funny but if you're TOO corny, then nvm (Although some people like that) just have a normal conversation with her.
