<p>lol, your son should ask him why he should care if he uses the heat in his room or not. His share of the bill is 50 percent. Maybe the kid can find an illegal unheated basement to rent alone in the future. Meanwhile he is stuck in the civilized world where roommates split utilities unless prior arrangements are made. He is also free not to use the outlets, lights or fridge or hot water but his share is still half. He does not get to unilaterally make up his own rules.</p>
