When the furnace breaks and you wake up in a house that is only fifty-four degrees on a morning when the frost is so thick it looks like it snowed overnight, that's a good time to wear a hat inside the house.
When someone in the house finally figures out how to wire the thermostat to jumpstart the furnace and the sweet sound of the blowers fills the air only moments before the heat iteslf arrives, that's when you'll find the dachshund staking out his place by the register under the sink. Don't step on him, he's just trying to get warm. He doesn't have a hat to wear inside.
