Re: Girl Trouble
You have several choices:
1) you can follow her around putting yourself in a position to be noticed but then pretend to be looking at something else when she sees you. Some chicks like stalkers.
2) you can sit behind her and let her catch you sniffing her hair. At the very least, you get a few sniffs of hot chick.
3) sit next to her, dump a soda in her lap, and then bust out some papertowels and wipe it up. Make sure you really dry off her crotch because NOBODY wants a wet sticky crotch in class (this is my favorite)
4) pretend to be her friend. be her emotional tampon. Eventually she'll tire of talking to you about all the guys she's fucking and give you a shot. It may take a while, and will likely put you in a mental institution, but it's safe.
finally, the one most likely to work:
5) say "hi. my name is <insert name here>. I'm in <insert name of class> with you. Would you like to go out tonight?"
there are obviously other options, but these are the ones I have/have seen employed most often. The best advice you will ever get with this is: JAHOYFT. Just Ask Her Out You F*cking Tool. I have shamelessly stolen this from another forum, but it's the best chick advice you'll ever get.
