It’s not my story, but it didn’t sound like it.

This happened in Soviet times.
The usual sanatorium of the Academy of Sciences, filled with staff of the middle hand - procedures, walks, gossip, in general, boredom is deadly. And then there was a rumor – an academic must come! The event! On the indicated day, curious people actually saw a car coming up from which a solid gray-haired man came out. and sympathetic. He was followed by an elderly woman, a woman. They went to the sanatorium to rest and be treated.
The wife of the celebrity constantly stirred around her husband, cared for him. He took all the care with tired kindness. And in the dining room they sat next to a cute young lady. The woman assessed the situation for a few days. He assessed and went to attack. After all, academic, this is such a chance, and why does he have such a silver old lady next to him? And gradually (the barbecue was literate and insidious) the novel began to bind. They are already walking together, and they are sitting on the benches, and so on,... in general, love is not a joke.
And when everything became clear, the wife could not withstand and went to find out the relationship with the invader. She just approached her and asked, very politely, “Please tell me, why do you want my husband?”
In response – a bunch of crazy phrases about love, freedom, fate, and so on.
The elderly woman said, “But you know, he’s a very sick man. He needs constant care, in addition, he must follow a strict diet, not every woman will withstand it.
The young woman rejoiced - it is not understandable that for the salary of an academic you can organize a great paid care, not necessarily at the same time turning into such a worried creature as her interlocutor.
The elderly lady looked at the young girl for a few seconds, and then calmly said, “I understand. But the fact is that the academic is me.”
