curiouser and curiouser

so i just had a discussion with someone about TA's and crushes and where the lines are drawn. why is it that crushes are always had on the most inappropriate people? no one ever has a crush on someone who is readily available. and its not like it's this planned thing. stupid crushes on unavailable people seem to just be the way it goes. anyway, we decided that TA crushes are probably not a good idea and that all feelings should be immediately dismissed. concentrating in class/lab/tutorial is hard enough without that kind of distraction.
