Only two that I truly consider friends -- been friends with them since I was a kid. A few more that I am cool with from school/work but not close enough for a "friend" status.
Yes, my friends are mostly white. In college, I really haven't met many ethnic minorities that I constantly see. For example, I don't think there's a single black guy in my building of at least 300 people. There's about two black girls, and a couple Hispanic ones as well. It's so strange, as I always expected my college experience to be more diverse.
