Do you Facebook? I do. Recently, I was bored and was looking at a person’s friends list who I have as a friend. I noticed that there are several of my friends listed as their friends also. I’m not jealous or trying to not share friends, but I know for a fact that these people have never met, or probably never even heard of each other.

Facebook is a social networking site, so maybe this is what it is for? The friends Facebook suggests should be my friends whether I know them or not? Someone please help me understand.
