I loved my freshman year of college! It was a chance to make a clean break from high school, which I didn't really like because I never felt like I really fit in. I joined Phi Sig, which obviously kicked ass, and I learned a few important lessons:
1. Keystone Ice tastes really, really bad
2. Partying till 5 in the morning night after night does not do the body good
3. If you meet a good looking girl, don't get so drunk that you can't remember her the next day
4. Running away from the RA's generally is not a good idea
These are a couple of the things that I can think of off the top of my head, I'll probably come up with a few more later. Hopefully this next year (my junior year) will be the best ever!
