Ethan: Mom, you said you were going to pick me up at 4 o’clock.
Mom: Sorry, my class got out at 3:45 instead of 3:15!
Ethan: Uh oh.
Mom: I know. Imagine my surprise–that’s a whole 30 minutes longer!
Ethan: Did you run out of lesson?
Mom: Well I stretched it for as long as I could…
Ethan: Next time just say ‘Well I’m out of lesson plan, anyone for Hangman?’
Mom: Good idea.
