I dunno about you, but my priorities in life consist of keeping healthy above most other things. I don't sleep nearly enough, and you really aught to know what that can do to you. I mean, you DID just have a big thing about how poorly you've been sleeping...you can't deny that getting some needed Z's is a worthy undertaking. My parents will be gone so my time won't be very occupied, so I'm going to take advantage of the opportunity to catch up on sleep.
Besides, what else would I do? I'm not a partier, and I value the trust my parents have in me not to act irresponsibly. I know that your college years are the years you're supposed to let it all hang out and do whatever you want, but what I want is to be a half-decent human being and not disappoint my parents.
The party life isn't for me...for one thing I absolutely hate drunk people. I hate people in general, for that matter...so when I get the chance to turn my back on everyone else and be comfortably alone, I'm glad to take it.
