I battle every day with my girlfriend she turns it to 78-80 and I turn it back down to 72. Everyday all I hear is it is freezing in here and I feel fine but she will say the kids rooms are too cold.. I have to go outside which right now is -3 to feel better, not only that but in the winter time you should not sleep without blankets(which I do because its so hot)!! I swear we are at a battle now so where does everyone else keep there's set at so I know I am not the crazy one??
