I'm both disturbed and a little proud of my son's budding manipulation skills...
Kyle: Dad, I saw a new book at the back of the car. Can you get it for me?
Me: I don't know where that came from. It might be for somebody else. Let's wait and ask your mom.
Kyle: You know, Mom doesn't have to be the boss of you.
Me: She's not. We make decisions together.
Kyle: Well then, you can just decide to go get the book.
Me: No. Let's wait and ask who she bought it for.
Kyle: Hmmm. Seems like mom is the boss of you.
Me: Nice try.
