When I was growing up my house did not have central air or heat. We always lived in older rent homes that were drafty and cold. I remember huddling around space heaters and sometimes even setting up shop in the kitchen, the warmest room in the house.
At night I would get into bed and snuggle under layers and layers of covers. At first I would be cold and my teeth would chatter but soon I would create a warm cocoon. My head would be the only thing sticking out and the difference between my body in the cocoon and my head in the cold was always so striking.
I thought about all this last night as I climbed into bed. My apartment building was built in the 1950s. It has a wall of windows which isn't a good insulator and it gets cold. I snuggled under the covers with only my head in the chill and was transported back in time. I felt like I was eight years old again, under the covers, protected from the world. If only that feeling could last forever.
