Girls get asked out constantly. By guys they know, by guys they don't know, guys who've only seen them once, etc. Hell, just earlier this afternoon one of my coworkers got asked out by a complete stranger.

If they're attractive, then some guy's definitely asked for their number, for a date, or even just sex -- 9 times out of 10, the people asking them out are douchebags. You can only be nice about it so many times before you get tired of being asked.

If they're not interested in you, just leave it at that. The problem's with them, not you. They shouldn't hafta give a reason to why they're rejecting you, because a simple no is enough. Anything more than that is just politeness.

A girl's not shallow because she's got standards. Attraction is very important. Some people get it through appearance, some through personality, and others through a combination of the two.

So the next time you get rejected, just say "Alright then," and leave it at that. Don't call her a bitch, don't demand an explanation, just walk away.
