I have to agree with a friend when she made the analogy that college is a lot like Summer Camp.

You get to live away from your parents and have to fend for yourself in a way. Instead of Arts and Crafts we have Algebra and Speech. The food isn't always the best and whenever you go home, you ask for homecooking. (Today I saw an add for Tuna Noodle Caserole on TV and both me and my roomate started drooling). 

Ways Life at College is different from life at home:

1) The graffiti. I am used to seeing has now been replaced by sidewalk chalk advertisements for clubs and activities
2) At home you can drive across town in 10-15 minutes, here you can walk to class in 10-15 minutes
3) If you show up for class 1 minute early you are on time. Now if you want a good seat, show up 10 minutes early.
4) You are afraid to do anything crazy/silly because people won't forget. Here I can run down the sidewalk with my sweatshirt spread out and make airplane noises and I don't care because a) people don't know my name and even if they say "hey I saw some weird girl pretending to be an airplane" they don't know who I am. b) they won't rember it's me.
5) In bed by 10:30-up at 7:00-----In bed by 12:00--up at 8:47. 8:30 classes are early and 7:30 is unimaginable
6) You can stay in shape by working out or joining a sports team. Now I just walk to class and don't worry about the freshman 15. 
7) Studying in high school is no fun. Studying in college SUCKS!
8) People make fan clubs based on a tv show or actor. Here, the hottest fan club is the Scooter Girl/Asian BB playing kid Fan Club on facebook

That's all I have for now, but I bet I can think up some more later.
