My son asked why I always say 'we have food at home' before we even leave the driveway

"Because," I said, buckling my seatbelt with the confidence of someone who's done this 847 times, "I can *hear* you thinking about the drive-thru."

He protested that he hadn't said anything yet.

Punchline

"Exactly. I'm **inter-snacking** your thoughts before they become expensive."
