The advert certainly didn't reflect my reality, but I have found that many women think it is appalling that I am not running myself ragged with domestic stuff. Therefore it doesn't surprise me that 8/10 women thought this was ok.
As an example, I ordered the Christmas presents online (not a time consuming task), husband wrapped them all, and set things up with batteries, downloading stuff etc. I wrote all the cards to my family (about 20), his family doesn't send cards so he didn't do any. We don't send joint cards. I mentioned this arrangement to everyone who was moaning to me about how much there was to do for Christmas and they all thought I should have done everything.
I will not be a martyr to my family but most people think I should be. Whether this is because I am quite vocal about not being a martyr I don't know, but it seems to me that most people insist on sticking to their sexist and stereotypical arrangements.
