Oh my gosh... sad...
First: Facebook is weak. If you have to have some sorta online habitat to attempt to spawn in, get a myspace, that way you can add, message and chat to your hearts content without being a complete wierdo.
Second: You memorized her email with one look??
Third: If you buddy knows her, tell him to stop being a c0ck and hook you up.
Fourth: In the case your buddy is c0ck and doesn't hook you up, get whatever it is you need in person.
From what i've read here i can tell you that you've lost her already. You are seeking her, not the other way around. She is the prize, not you. Change your mind state before you mack bro.
