Melody: Do chins grow?
Mommy: Yes. Every part of the body grows.
Melody: Is your chin bigger than mine?
She puts her chin against mine to compare size.
Melody: Why is your chin bigger than mine?
Mommy: Because I'm a grown-up.
Melody: Is Daddy's chin bigger than yours?
Mommy: Yes. And mine is bigger than yours. And yours is bigger than Charlie's.
Melody: Is it always that way?
Mommy: Well, if I'd married Jay Leno and had babies with him instead of Daddy, your chin would have already surpassed mine.
