I didn't care about school, or the people there. My grades were bad, and in six years I didn't make lasting friends except for a couple good guys (which I see rarely anyway). Usually I just slept or thought about other stuff for those 5-6 hours and then I went home as soon as the classes ended. It wasn't bad or anything, I just couldn't care less.
It's the same now with the job, btw.
Nowadays the only people I'm ok interacting with (on a constant basis) apart from my gf, are other online gamers.
Moral of the story: I really can't be bothered with social life.
