What's Nonsense?

Cade and Scott were talking the other day, and Scott said something (he can't remember what it was).

Cade's response was, "that's nonsense, Daddy!"

Because whatever it was that Scott had said was indeed not nonsense, Scott asked Cade, "What's nonsense?"

Cade's response: "It's something that doesn't make sense, Daddy."

Touché, Cade.
