I refuse to turn the heater on

Our electric bill was really high last month (almost $200), so I'm going back to being a thermostat nazi. After being 80 degrees yesterday, it is currently 36 degrees with a wind chill of 25. Gotta love Texas. In the past, I would get up in the morning and stay in my tank top and pajama pants and crank up the heat. I was just too lazy to get up and put on some extra clothes. I got up, and instead of turning on the heat, I put on an extra layer of clothes. Seriously, how hard was that?
