"Not... really. Sometimes-" He looked a bit guilty. "Sometimes I do. But people need me, so I put it aside. Sometimes, when it's cold and wet, I don't want to go out into it, but I need to. I'm needed and I have somewhere dry to come back to. I don't think I can get sick. I don't need sleep. I don't eat. I feel hot and cold, but I don't really sweat."

He had no real needs, but others did.
