Why is it colder INSIDE than OUTSIDE?

So clearly the temperature has dropped this week - by a lot. Anyone who knows me knows how much I absolutely LOVE the cold... but I'm not gonna lie, I'm still sort of enjoying it. Don't tell anyone. However, it's gotten cold enough that Sunday night we decided to cut the heat on for the first time.

The roomie turned up the thermostat, and we all went to bed. The next morning, it's roughly 36 degrees in my bedroom. I lay there for 40 minutes, beneath 4 blankets with my dog curled up next to me, absolutely dreading the inevitable. There would be no showering. I pulled on two shirts, a winter coat, jeans, and shoes before even making it out to the kitchen. My roommates were similarly dressed, huddling over the oven. All we needed was a trash can fire and we might have looked like we belonged in our neighborhood...

Clearly, our heat wasn't working. And of course, you never figure that out until you actually NEED the heat. After railing for an entire day aginst the landlord, I get home to find my roommate in the living room, wearing a hat, sweater, and several blankets. She says the landlord came over and explained why the heat wasn't working...

We didn't turn on the gas. Naturally, our heat is gas. After trying hard not to laugh at us, he explained that we needed to call and have them turn it on. Thanks.

Meanwhile, we have to wait at least 48 hours for them to come hook us up. Here's to space heaters and lots of blankets...
