Daddy: Look, Dmitri... (holding up his fingers one by one) one mouth, two ears, two nostrils, two eyes... how many is that.
Dmitri: (scoffing - like, "I'm not stupid, Dad!") Seven.
Me: Not eight.
Dmitri: (looking all proud) You forgot one.
Dmitri: You know, that hole in the back of your head where your hair goes in?
Huh? Michael and I exchanged glances. Dmitri rolled his eyes, turned around and pointed to the back of his head.
