I asked Emily to clean her room the other day. It was a disaster with dirty clothing and toys scattered all over the place. She looked at me and said innocently, "My floor is not dirty." I asked, "Then what are these things all over the floor?" "Oh, those..." she said (I could see the wheels turning in her little head) "Those are part of my floor. See--stuck!" and then she pretended to pry a shirt off the floor as evidence that it was, in fact, stuck tight.
