So a little while ago Paul comes bouncing into the room and asks, "What does it mean to covet?"
I answered "It means to want something."
"Oh" He said, and bounced back out.
A few minutes later he walks slowly back into the room and says "Well I'm not going to covet my neighbor's wife, because I don't want Mrs Kochenderfer, and Mr Lemar doesn't have a wife!"
Wow, how simple life is when your five.
