Numbers
Guys in the City baffle me. When you want them to call, they never do. When you hope they'll lose your number, they won't stop calling. A friend asked "Is it bad if I call a girl I met at a bar 3 weeks ago?" My response, "Well, it seems like you just happen to find her number in your jacket pocket and decided to call." Figures, that's more or less what happened. Why ask a girl for her number, if you're not going to call? Or at least, call while she still remembers who you are?
