Sure. I've had a crush on her since middle school (if anything she was the original crush, come to think of it), has always been nice and funny. We also have had a total of at most 5 classes together, and have spoken less than 100 words to each other. Compounded on the fact that you know she has a boyfriend, and beyond that is (supposedly) interested in black people more than white people (and I'm the living definition of Captain Whitey). You learn to just appreciate the eye candy and go after other ideas. Sure, you'll still contemplate it from time to time, but never really seriously.
