From the Memoirs of Queen Hortense:
He [Napoleon] even said to me one day : "People tell me you are clever. I don't know anything about it. I always feel as though you were ten years old. It is the same with Eugene. I have never been able to get used to hearing him reason out something logically." And the Emperor added : "That is the trouble with parents when they get old. They can never realize that children grow up, and sometimes could actually teach them a lesson."
