Eavesdropping on my boys this morning...
(After another petty argument)
Justin: Well, you're not real!
Kaleb: If I'm not real, then no one would tell Mommy that you fell off the deck. You'd still be lying there and couldn't get up. You'd just be lying there crying. No one would know where you are.
(It's funny and mean all at the same time...not to mention it happened more than a year ago....boys! )
