Context: Another friend of mine mentioned to me , just offhand , that he 's hung up on somebody , " hung up bad , " and I was dumbfounded for a minute trying to figure out how I 'd describe my own state . I was going to say that I ' m not hung up on anybody , and that that is unusual for me , and somewhat uncomfortable in its own right . Which seems weird - why should I prefer to be suffering unrequited passion , instead of just feeling nothing very much ?

Question: Who may I have a hang up about ?
Options:
0. Another friend of mine
1. None of the above choices .
2. Someone I do n't know
3. Nobody
Answer: 3
