put on a sweater!

Growing up, my Dad always used to tell me and Marit and Mom to put on sweaters instead of cranking up the thermostat. We would usually grumble and then turn up the heat when he wasn't looking. But now I understand my Dad's wisdom...well, I mean, I've known he was wise for a long time, but this thermostat wisdom makes much more sense to me now. I've become my Dad, you see. My roommate Vibeke loves to turn the heat WAY up, and when she's not looking, I turn it down and put on a sweater or crawl under a blanket. When I see 28 degrees celsius registering on the heater my skin begins to crawl because I know that means a monster heating bill next month...and can I afford a monster heating bill??? NO, I CAN'T! So Vibeke, why don't you put on a sweater?
