I have 126.
Most are people I knew in the past and never was close. A few are real friends either current or best friends from the past when I lived somewhere else. I also have a couple family members on there. There are like a couple friends I have no idea who they are, but since we had so many mutual friends I added them. My memory kinda sucks from high school and grade school, so I'm always afraid to deny someone thinking I didn't know them and I did and just don't remember them.
One guy that I don't know who he is, a bunch of my friends (whose mutual friends with him) didn't know him either and we all started to try to figure out who he was. One of my friends was worried he was an undercover cop trying to gather evidence for drug related crimes. But anyway, I decided he does a lot of the mafia wars and farmville and other bs I can't get into and was probably adding friends to get help since I always see them posting how they need some bricks for something. Anyway, a girl on there I have no idea who she is, but she and I have gotten along very well and we talk a lot. Her name sounds familiar, but she hasn't brought up how we know each other.
