i don't get it

ok well i am supposed to be hard at work finishing a paper on grice's maxims, but i can't seem to concentrate on that. kristin is coming here with pizza soon, and i am waiting in anticipation. plus, i've been feeling really weak from a change in medicine and it's driving me insane. even with a full stomach i feel like my body is weighted down by lead weights and it blows.


but seriously though, i don't understand the deal with people who can manage to smoke and drink and do drugs just about every day while they're in school. is it an addiction? is it a desire to escape pressure from friends, family, school? is it a vice for a subordinate psychological issue? do they not want to be in school? do they understand that they or their parents aren't paying for them to fail or have expensive days away from home. is it a maturity thing? what is it? is there no one concrete answer? some one tell me, i'm dying to know.
