"Knock, Knock..."

We have a little step stool in the half bathroom for Ethan to stand on and use the sink. The other morning after he was done eating breakfast he ran off to the bathroom in a hurry and closed the door. I went to see what on earth he was doing and opened the door. He was at the sink washing his hands, turned and looked at me and said "knock", with an attitude! :-) He gets funnier everyday, how truly blessed we are to have Ethan in our lives!
