Miss Chu,
I am afraid only you and me are in this chat room.

It is not bad today here, as far as weather is concerned. Yesterday it was -15C and today it is -10C. Not bad at all. I am lucky that we have heating system in both working place and home -- always around 16 - 22C.
Why did you say that your fingers were frosted? Is there any heating system in your dorm? You pay your rent and should be provided with a comfortable living environment. Should you? If not, you have to talk to the authority of your college and protest.
