Yesterday I was hanging out with Bruno age 2 (almost 3!) and I said, "Oh Bruno, do you know this song? "Heads, shoulders, knees and toes..." and he cut me off and said, "Oh I know that song, I know that song. I want to sing it all by myself. Head, shoulders..." here he gets a little lost, hesitates, thinking, and then touches his belly, "knees"...again he hesitates, thinking, then... "weenis..."
