the evil brain

I forgot the best part of last night. When I got home from the interview I pulled Matthias aside and I asked him if he'd been wrestling at school. I could tell right away, by his face, that he had been. So after denying it the first time, I lowered my voice a little and asked again.
"Matthias, are you wrestling with boys at school in class?"
"I don't want to, but my brain makes me do it."
Trying to conceal a smile I ask,"You're brain tells you to wrestle."
"Yeah."
So I said what any good parent would say, "Well then buddy, next time your brain tells you to do that, you say 'no'. Don't listen to your brain."
