The blanket, or the thermostat?

When it’s cold in your bedroom, do you prefer to turn up the thermostat or to crawl under your bed blankets? I want the wool blankets, some of them older than you are! The thermostat is okay, but nothing else rivals the comfort and satisfaction of crawling from a chilly Autumn environment into one of instant, soft warmth that you can easily modulate by pushing blankets off you or pulling them onto you and not having to haul your ass out of the bed to twist a knob on a machine; and, if a lover is in the bed with you, it is obviously “no contest.” I imagine that crawling under the sheets (or animal skins) is an atavistic pleasure dating back to the Stone Age. How about you?
