Lying in bed in an early morning haze, I ask myself, “Is it Friday or Saturday?”
Saturday? Please, oh, please, oh please? Please let it be Saturday.
It’s too early to think, but I force myself: “Was yesterday Thursday or Friday?”
It had to be Friday if today is Saturday.
“What did I do yesterday? School…”
You do school on Fridays!
“Isn’t that noise Bill’s alarm clock?”
No, no, you’re only dreaming…
“If that’s his alarm clock, it can’t be Saturday. It must be Friday.”
NOOOOOO!
“Bummer.”

There's no winning, either. On Saturdays I wake up early worried that it's actually Friday and I should be starting work.
