Ethan cracks me up.
This morning as I was making breakfast, he was running laps (into the kitchen, through Daddy's office, out to the living room and back through the kitchen) and saying "FAST" and running really fast, then saying, "S.L.O.W" and running really slow. He even asked me to stop and watch him. He explained the difference between fast and slow and gave me a demonstration and telling me what animals go fast and which go slow.
I thought it was pretty cool of him. He's growing up so fast.
