What clothes?

This evening after getting home from dinner, Michael got Sean in the bath. I had gotten in the shower, and Sean wanted to race to get ready for bed. Naturally to get him to cooperate better with his dad I took my time, and he won. Since I was still "trying" to finish getting ready, I asked him to put away the dirty clothes on the floor. Sean looked behind him at the pile on the floor, turned back around and started to pretend he was looking at the ceiling and said, "What clothes?" Michael and I had to laugh, and Sean put the clothes up.
