John got a concussion over the weekend, playing hockey at a friend’s. He came home yesterday before noon. Somewhere during the afternoon we had a little conversation…
Me: You might have lost some brain cells!
Him: Not might.
Me: What?
Him: There are studies that show that parts of your brain can die.
Me: (Haha! Then serious.) Does that depress you?
Him: No.
Me: You might have lowered your IQ a few points.
Him: Oh. It’s ok. I’ve got lots to spare. 
That’s when I’d have taken back the muffins I gave him out of pity. But he’d ate them already.
