When I was 8, I told my mom I wanted to be a garbage man because I figured they got off really early to play since they were up so early to throw away trash, and they were providing a societal benefit that didn't require schooling (My teacher, Mrs. Morgan, was a complete asshole). My 11 year old nephew wants to go to the Navy to cook because he loves cooking and once saw a show about the mess halls there.
Kids have kid dreams.
