Well, it depends on if family members count... Most of the people that I'm closest to are my relatives, lol.
But anyway, I'm not really sure; I'm not in the mood to count right now. XD There are so many people that I know that I like a lot, but only a few of them are my close friends. I have a lot of friends my age in real life, (that aren't relatives) but I get along with two of them the best. We're all three friends, and we have a lot of fun together!
I'm also really close with a few of my online friends. One is my friend in England; we write letters and send lots of things to each other in real life, and talk on the phone sometimes. Another that I know very well is a member here; he has almost all of the same interests as I do, and he's one of my best friends even though we haven't met in real life. ^_^ I love talking to him!
And I'd name more, but I don't want to rant, lol...
