Yes, at work. I walked into the bathroom and this coworker I didn't know was violently twerking in front of the mirror while whipping her hair around. Within a week we were friends. Also, I decided to make an associate a friend, and then he became partner and I flat out said "Don't forget the little people who were friends with you from the beginning!" and we've stayed friends. I just thought he seemed smart and kind which are two of my three requirements for friends, so went for it.
