We're knackered. A couple of generations of women have come of age trying to "have it all", with varying degrees of success, and most of us are exhausted by it. We are told to be successful career women, good mums and partners, devoted friends, maintain a social life, a beautiful home, a scintillating sex life, an interest in current affairs, an attractive, youthful appearance, and without much help - really, the traditional "wifely duties" haven't gone away and are still, in most cases, largely performed by women, and we've added to them the career pressure only felt by men in the 1950s ideal.
Small wonder that even knowing the reality was very different, the fantasy has a certain appeal, when it's 10pm and you are just finally sitting down after a busy day at work, followed by a mad dash to pick the kids up, whizz round the supermarket because there's nothing in for dinner, feed everyone, bath and bed the littlest DCs, help the older ones with their homework, shout at DH to load the dishwasher and take the bin out, because frankly thats the least he could do, stick a load of washing on because you actually are about to run out of clean knickers, should probably run the Hoover round too because god knows when it was last done, but first the kids toys need to be picked up off the floor, and then finally, finally, you can collapse - but best check the Blackberry first, because something's bound to have kicked off at work after you left (just) in time to pick the kids up....
Yes, I can understand the appeal of the fantasy!
