"There's something going on around here"

It's odd really, in the last hour, I've had two people say hello (people that i don't even know) to me between classes. One person knew my name (no, i still have no idea who it is/was), and the other person introduced themselves to me... Very odd, I would have never expected that to happen, but i guess i'm just used to the people being unsociable. I know I shouldn't be surprised, but it still does surprise me. College is so great!!! I love it, and most of my classes. I'm going off about 3 hours of sleep right now, so i think i'll leave it at that, before i say something i might not want to.
