Heating

Has anyone else got the heating off? I actually don't mind a colder house but this season has been particularly bad. My flatmate however is never very keen to turn on the heating outside its alotted schedule. I think (hope) its a money issue. Whilst I normally keep quiet about it I have to say that she currently looks more than a little strange. She has a visitor with her and they are both sat around the advent candles, shivering. Huh!!!!! Surely a visitor would merit switching the heating on for at least a little while?!
