I don't like needy people. Anyone agree?

Long story short. So I am at a friendly 4th of July get together last night, my wife introduces me to a couple who she knows from her girlfriend work. Then she runs off with her with her friend and leaves me with the guy that I don't know from Adam, putting me in an awkward situation with nothing to really talk about. I hardly think I was unfriendly. We made small talk with a few other people, but I wasn't going to sit and entertain the guy one on one all day. He basically just didn't seem to have much in common with any of us, so he mostly stood there and didn't add much to the conversation. Today my wife tells me she talked to her friend and the guy feels like we weren't very friendly to him. Now my wife is mad at me because I won't call this guy and apologize. Apologize for what? People like this infuriate me, and the guy too. Sorry Honey LOL. I just don't understand people like this. What do they want you to do roll out the red carpet for them? Geez.
