Although there are some rare people in this world who actually enjoy doing housework, most only do it because they know somebody has to.
And when you're doing something you don't enjoy, it can be pretty easy to get a distorted perception of how much work you're actually doing and how long it takes. With this in mind, it's not exactly a surprise that the division of household labor would be such a common subject for arguments within a married couple.
And unfortunately, some women have found that these arguments reveal just how unappreciated and taken for granted the work they do truly is. But for one wife, that's not going to happen without some pretty significant consequences.
