Conversation with Daniel

Have you ever tried to explain to a three year old that his first name is not the one he is called by? His name is Paul Daniel Petersen, and I was trying to explain his name and that he had the same name as Daddy. I said, "Your name is the same, you are both Paul, but you are Paul Daniel." Daniel replied, "No his name is Paul Daddy. My name is Daniel." Guess we will wait another year to explain that one.
