Actually I think by not making it something to battle at the begriming when it does come up it is not argumentative. By saying we will discuss instead of giving the answer before the event happens creates the argument. I am not turning my air conditioner to refrigerator because I declared I will lower the air. We will discuss actually also says your comfort is important but not more important then my common sense. So sometimes I will lower a degree or two, I bought a nice stand up fan, there is a ceiling fan and one time I had a person who wanted refrigerator, I found some stupid thing of a fan you can wear to sleep but it had an ice pack you put in the fan haha. It wasn't an argument because both sides were respected.
