brain changes

The elevator is going up. Inside it are two teen-agers and me. Says one teen-ager to the other, “These pants are so ugly, but they sure are warm!”
Says the other, ”Well, it doesn’t matter what they look like, as long as they are warm.”
I leave the elevator in a state of confusion. Something is wrong with this conversation. If I had a hearing aid, I would definitely check it for evidence of tampering by aliens. If these were the olden days, I would expect a smiling TV host to jump aboard and shout, ”Wendy edey, you’re on Candid Camera!”
But I don’t have a hearing aid, and this is 2009, and these really are teen-agers. And then it comes to me. This overheard conversation is clear undisputable evidence that brain changes can result from prolonged periods of almost freezing to death in March when spring ought to be coming!
