"It's no problem," John said, moving so that he was sitting on the windowsill instead of just leaning on it. If there was going to be a longer conversation, he didn't want to just be floating there outside the window. People might start asking questions. "Like I said, I just got here, and I don't have any jobs or anything. I'm John, by the way."

Introductions were necessary, since it would be slightly less weird for him to hang around if they weren't strangers.
