So to sleep on the sleeping porch required preparation. First, you put on long underwear, pajamas, jeans, a sweatshirt, your grandfather’s old cardigan and bathrobe, two pairs of woolen socks on your feet and another on your hands, and a hat with earflaps tied beneath the chin.Then you climbed into bed and were immediately covered with a dozen bed blankets, three horse blankets, all the household overcoats, a canvas tarpaulin, and a piece of old carpet. I’m not sure that they didn’t lay an old wardrobe on top of that, just to hold everything down. It was like sleeping under a dead horse. For the first minute or so it was unimaginably cold, shockingly cold, but gradually your body heat seeped in and you became warm and happy in a way you would not have believed possible only a minute or two before. It was bliss. Or at least it was until you moved a muscle. The warmth, you discovered, extended only to the edge of your skin and not a micron farther. There wasn’t any possibility of shifting positions. If you so much as flexed a finger or bent a knee, it was like plunging them into liquid nitrogen.
