My roommate Betty is costing me a fortune and driving me insane. The two of us first moved in while we were in the Spring last year, when the outside temperature was wonderfully mild. I hoped we could trim costs by simply opening the windows. Unfortunately, when the windows were wide open, Betty would lower the control device thermostat and start up the a/c. I’d point out that the cool air was flying straight out the window, and she’d explain that she loved the combination of fresh air and air conditioner. Once the heat and humidity of summertime arrived, I was glad to operate the a/c. I was unwilling, but, to leave the a/c blasting while we were both at work. No matter how many zillion times I reminded Betty to bump up the control device thermostat before heading out the door, I’d come home to a freezing freezing cold apartment. Now, the outside temperature is down in the teens and the situation is even worse. Betty would like to run the furnace at maximum capacity at all times. Whether we’re at home, at work or sound asleep, she has the control device thermostat cranked up to the point that I’m sweaty. I often catch her opening a window to let in some fresh air.
