As you have been on the road, what have you been hearing from readers about A RELIABLE WIFE?RG: The most interesting question came from a young man in his 30s who asked me to discuss the relationship between love and aging. We think when we’re young that, as we get older, our passions and enthusiasms will fade, will lose their hold on us, and we will enter into some more gentle phase. I don’t find it to be true. Our passions, in fact, intensify, like a sauce that has been reduced to its essence by long slow simmering over a low flame.
