The three women couldn't help overhearing snatches of the conversation – really more of an argument – taking place at the restaurant booth next to theirs.

A man's voice rather adamantly declared: "I just can't believe with all those planets there's not someone up there somewhere."

His female companion was equally certain: "If so, don't you think someone besides a few paranoids would have seen something of them by now?"

And so the argument continued. Only by refusing absolutely to make eye contact did Sam, Vala, and Cassie manage to avoid collapsing into helpless laughter until after the arguing couple had left.
