I was discussing Michael J. Fox with Marcus - he is best known in the under-sixes as the voice of Stuart Little the animatronic mouse. We told Marcus about MJF's Parkinson's disease. I said that MJF was a top person, who appreciated that he was better off than a lot of people, with all his money and fame. A lot of people wish they had money and fame, etc.
Marcus asked "but why do people want foam?"
