No more than 2, no less than 0. I'm not sure where the line between friend and close acquaintance lies, or the difference between a friend and a close friend, between being friend-like and friendly, ect ect. If asked I'm more likely to say I like someone as a person then to say I'm friends with them, I'm too unfamiliar with the meaning of the word to give sincere answers.
I have 0 real friends. I know several people on a casual basis, but not that I would call friends. I have 1 internet friend; outside this site; which I don't think counts either.
Two. I have a few acquaintances from high school that I'll talk to if I bump into them. I also consider my siblings close friends since we all share similar interests and are close.
Like many other people who've posted here. I am also a loner. I've got 1 online friend if that counts.
And of course I've got you guys.
But real life-wise no one. I've had "friends". But they all stop talking to me at some point.
