"Are you a housewife?"

I agree with navane- you handled that well.
May I ask what your estimate on his age is? The transition to 2-income families being the norm was roughly 1972-1980, and finally hitting the rural areas during the farm-crisis years of the 1980s. I'd be interested to see when he retired as being a doctor he should have been aware of this transition with his patients.
