Given the social barbs aimed, it was good to see a bit of balance pushed in to the argument. I have friends where the wife is eleven years older than her husband, and I am twenty-one years older than my my wife. What is the problem? There is a difficulty in the ten-to-twenty age period when people can misinterpret their feelings (no, they can misinterpret their feelings at any time) and end up realising that their feelings are gone. And at any time in the following decades they can reinterpret their relationship as one to continue, or one to finish.
