Dear Roommate

Dear Roommate,
I've noticed a new trend that is not working out in my favor. This trend involves our air conditioner. You see, roommate, when the weather turns cold outside, it doesn't have to turn cold inside too. We have this beautiful thing called a radiator which emits life-giving heat. Now roommate, I know you know we have a radiator because occasionally the pipes bang together and sound like someone is firing a shotgun inside of our radiator. It's a little hard to miss.
Roommate, I would like to thank you for one thing. I actually didn't know that our air conditioning went down to 60 degrees. What a pleasant surprise. However, when the temperature outside is only 50 degrees, 60 degrees isn't actually that pleasant. Unless you want me to don a red suit and start saying "ho ho ho" there is no reason for our room to feel like the north pole.
Contrary to your belief, I actually don't enjoy waking up for my 8AM class and feeling like I'm touching an icicle as I climb down my ladder. I feel like my next step may be to grow feathers and become a penguin, since clearly our room is the arctic circle.
So, in conclusion roommate, we need to turn up the heat, and turn off the air conditioner. If we don't remedy this situation soon, plaster dust won't be the only white powder falling from our ceiling.
Sincerly,
Your frost bitten roommate
