This is going to sound very odd, but I don't think I ever learned how to make friends. I am 28 years old, intelligent, kind, fun, etc.. yet I have no friends. I see how other people are able to just jump into conversations with people, and subsequently wind up hanging out with these people, getting invited to parties, etc., but I just don't have any idea how to do that and feel very uneasy and clueless about the whole thing. Any suggestions?
