I hardly know him...

Outside goofing around...
Me: "What's your favorite subject at school these days?"
E: "You probably know."
Me: "P.E.?"
E: "That's not even a subject."
Me: "I know, but it's what you always say---"
E: "---But it's not a subject. My favorite subject is math."
Me: "That was going to be my next guess."
E: "Yeah. Because math is a subject."
Me: "I know. So what's your favorite time of the day at school?"
E: "You probably know."
Me: "P.E.?"
E: "Why do you keep talking about P.E.?"
Me: "You love P.E."
E: "But it's not my favorite time of the day. Lunch is my favorite time of the day."
Me: "Lunch? Not recess?"
E: "I'm growing, like, an inch a day. I need lots of food to make that happen."
Me: "Oh, ok."
E: "It's like you don't even know me sometimes, silly Mom."
