It's chilly and sprinkling outside. Here's what I said to my eight-year-old about, oh, fifteen minutes ago when I sent him outside to play: "If you get cold, come in and get a jacket."
How stupid is that?
First of all, he's eight. He knows what to do when he gets cold. It's not rocket science. That ranks right up there with "Be careful" (duh) and "Don't fall." (Also duh.)
Second, I just looked outside. Not only is he not wearing a coat, he's taken off his shirt.
