"It must be really rare if no on even mentions it." With a slight groan of annoyance, Luke pressed the heel of one hand against his temple, then dragged his fingers back through his hair.

"I tried to tell him he was wrong, and then I thought thought maybe it was just something from his world?" But he guessed he could buy that it just wasn't that common. Luke had never thought about it. "It's probably still not that rare, there, though. ...I think he thought I was kind of crazy for not believing him."
