School? Jeez. If I need to see a band, and I can't get the next day off work, unless they are a band touring from overseas, I usually don't bother, because I'll be able to see them again in the next year or so, but when I was back in school I would just go to a gig, and then to school and sleep all day.
You just cannot get fired from school for sleeping, no matter how hard you try.
