I agree. The best thing about college was that all my friends were from different walks of life. We just happened to be friends because we were assigned as roommates. My friends included a pot head, a meat head, a brooklyn hipster and some in-between. We bonded mostly over drinking and dating. It was a great time, but after college we didn't work in the same industry so some moved away. We eventually started getting in serious relationships and stopped drinking as much so obviously there was less to hold us together.

Today my friends are mostly people I used to work with and we have more in common, although we're still pretty different since we came together by accident of employer
