"I was telling somebody about in grammar school we used to have the duck-and-cover drills where we'd have to go down to a fallout shelter in the basement. We'd sit on our butts on the ground next to the wall with a textbook over our heads and our knees sort of drawn up to our chest. I don't think they still do that. They're sort of sobering. You leave recess and come in for the apocalypse drill."
