When both partners do their fair share of domestic stuff, but one of you doesn't have the same standards as the other, does it usually fall to the 'fussier' party to do more of the housework? I know that if I suddenly decided I wanted a show-home standard pristine house, DH would not be on board with that, he prefers the bare minimum approach (as do I). And it would mean that the amount of housework we do would become unequal.
I'm really thinking of two friends of mine, who have lovely tidy houses, most likely cleaner than mine, and who say that their DPs just don't clean to the standard that they do. I think (privately, in my head) that if they could meet their DPs somewhere in the middle they would have less to complain about regarding their DPs not pulling their weight.
