In that case, I agree.
My current spouse leaves all the doors open because "it helps the heat circulate when the heating's on". When I incredulously explained to her that that's fucking stupid and closing the doors throughout the house when using the heating is a far quicker, smarter, more efficient and, frankly, the only way to do it, she countered that her dad taught her to do it that way. And she's right enough, he does as well. Leaves all the doors in his house open. Drives me fucking mad. Whenever we visit him I go round and shut the doors to the bedrooms, bathroom etc and he comes along behind me and opens them again without saying anything. Endlessly and silently we play out this passive agressive war of attrition with no clear victory for either side.
