A while back I recall a couple of my friends who both happened to be math teachers and also married to each other. Their names don’t matter, I’ll call them Karen and George. Both were near retirement age and they’d been married for over 40 years.
One day, Karen suspected that George was doing some stuff extra-maritally that perhaps he should not. Karen chose to confront George and he admitted that he was seeing a woman in her early twenties. He only went with her because the sex was fantastic! Karen seemed to understand and admitted that she to was going around with a young man in his twenties and she decide to tell George.
Both being good math teachers, she said “George, I’m seeing a younger man as well, and like you it’s just for the sex. I think it’s great that twenty goes into sixty a lot more than sixty goes into twenty.”
