Luke: I'm finished.
Me: You only ate one piece of pizza.
Luke: But it was a big piece.
Me: I know, but you usually eat at least 2 or 3.
Luke: I'm full.
Me: Are you sure? I really think you should eat one more.
Luke: I'm sure.
Me: And you won't be asking for more food in an hour?
Me: (glances at clock and makes mental note of the time)
[1 hour and 4 minutes later]
Luke: Mommy, I'm hungry, can I have a snack?
