Prom Boob Slip that I can't see

Some dude posted this vid of a girl who almost shows her nip. I find it interesting that we put so much emphasis on things that we want to see. Usually things we hope to see are not as interesting as we imagined, like Britney's or Lindsay's vaginas or any Will Smith movie.

She's kind of a pretty girl. I hope she has fun at the prom or whatever.
