I have five of my classmates from college. We just stuck with each other after college and kept in close contact. I reflected upon friendships one day and concluded that my friendship with them is unbreakable regardless of time and distance.
Another one is my token straight guy best friend that I fell in love with.

He was instrumental as my inspiration as I pulled myself out of depression and managed to revive my career, although we're both busy nowadays so we haven't talked in a while.
The last one is currently the friend that I am constantly in contact with since he's a co-worker. He's the only person out of my "work friends" that has proven his loyalty, and that's pretty hard to come by nowadays, so it really meant a lot to me.
So I guess I have 7.
