Ask her if she's seen your pocket protector anywhere and then strike up conversation. Make her laugh. If you can make a girl laugh - you can make her do anything...so says Marilyn Monroe. I don't know if she'd be the first person I'd ask for advice, but hey...the quote makes sense to me...
"So tonight, when you're wondering what to say, or how you look, or whether or not she likes you, just remember, she is already out with you. That means she said yes when she could have said no. That means she made a plan when she could have just blown you off. So that means it is no longer your job to try to make her like you. It is your job not to mess it up."
