I'm a little awkward at personal conversations, too. One thing that helped, believe it or not, was reading joke books. I don't mean I go up to people and ask, "Hey, want to hear a joke?" but reading the jokes helped me to have snappy answers and to be funnier. I have a hard time, though, if I don't know much about what a conversation already going on. I don't do much with my days, so I don't have much to say about it.
