In the wee small hours of the morning.

Sam: (appearing at my bedside, looking far too awake) We need to get invitations.
Me: Ergh. Huh? What time is it?
Sam: We need to get invitations for the Guilty Party.
Me: For what?
Sam: The Guilty Party.
Me: What’s that?
Sam: You know. The Guilty Party. And at the end of the party, the mystery is revealed!
Me: Oh. Wait. I think you’ve gotten something mixed up . . . Seriously, it’s only 5 am? Go back to bed!
