Wasn't accusing you or anything, I was actually curious, as you seem to be generally extremely intelligent (and condescending, but that's neither here nor there).
Although I only know one kid (and by know I mean I've spoken with him occasionally) who regularly cuts class. He was recently involved in a drug deal in which he was trying to sell stolen pot. He now has several nasty scars all down his face. Which isn't to say that this is what happens to people who skip class or anything.
Anyhow, skipping class to smoke is one thing. If you have a reason (such as reading or whatever) it's different. The former makes you a dumbass. The latter just makes you absent.
