Spotless house? - PAH!
I was a lone parent (a bit like the Lone Ranger but with a chid rather than a horse ), for many(13) years so all was on my shoulders anyway - both the 'manly' and the 'womanly' tasks. With husband we have always operated on the fairest system, so when we are both around we both do what needs to be done. Currently I am at home whilst he is out of the house 14 hours a day, so the domestic stuff rests with me. That's fine by us both.
I grew up in a household where my parents just got on with things, e.g. Dad was home before Mum so he got that night's meal sorted. There was little debate about it, things just got done.
It is ingrained to a greater extent that the woman 'takes care' of things. The part of the article that looked at how once women went beyond the equality threshold their domestic chores increased I can well believe. It would be their way of apologising and making amends for being successful, and showing their femininity through housework. Horrifying thought isn't it?
