It's cold today. Really cold. And because of some peculiarities with our old house, it's cold inside, too. In the winter, we close off the outer rooms of the house, only making brief foraging trips into them for particular items. We live in the kitchen, the living room, and the bedroom, camping out with our laptops and building little work stations wherever it feels warmest. (In warmer seasons GF and I each have our own separate rooms for study/office space, since we work at home a lot.) I cook things in the oven to help warm us up and we wear hats indoors. We exercise a lot, and always shower at the gym since it's much warmer there than at home.
Depending on my mood, it's either miserable or kind of fun. Tonight it's going to be super cold, so we'll retreat further into just the bedroom, giving up on trying to heat the living room enough. Get the dogs into the bed with us, and read and watch movies on the laptop. I know a lot of people actually manage to go out and do things on winter evenings, but my impulse is to just curl up and stay inside.
