I had to blog this one before I forgot :)
I called Gavin in to eat lunch. Here's the conversation we had:
Mom: "Gavin, it's time to come in and eat lunch."
Gavin: "Well, Mom, I had like 8 muffins for breakfast (he had 2). Half of the muffins I ate were for breakfast and the other half were for my lunch."
I love the logic of a 5 year old :)
