No heat until January

J and I sometimes like to challenge ourselves. As in, "Hey, let's not turn our heat on until January!" "Sounds perfect!"

I would just like to say that I've been working the last hour and a half on wedding invitations in my office wearing sweatpants, wool socks and slippers, a turtleneck sweater, a hoodie sweatshirt, a wool hat, a blanket across my lap, and a pair of gloves that I had to remove to type this.

My computer says it's 68 outside, which I'm not sure I believe, but it's frickin' freezing in our house. Why? Someone please explain how that's possible.
