I have always had an appreciation for the 'stay-at-home mum'. This was the role my wife was happy to fulfil in the early days when children came onto the scene. She wanted to be there when the kids came home from school.
I enjoyed making others think when they asked me if my wife worked. I always said 'Yes' with great conviction and when further discussion revealed what she did, they (almost exclusively males) were ready to apply the 'only a housewife' tag. It is simply amazing how easy it was to embarass some people who really did not appreciate that work!
I even extended this approach when I was across the desk from someone filling in some HR form...
Q. Does your wife work?
A. Yes
Q. How much is she paid each week?
A. Nothing.
... and then it gets awkward - for the other person, not for me
This is something I have been doing long before it became a popular crusade within the social consciousness - and I'd happily do it over again.
