My friend has been married for many years without children.

His mother-in-law thought his wife was infertile.
She never gave her wife a good look, and the husband was caught in the middle, feeling helpless.
One day, the husband brought home a medical report that said: the husband cannot father children.
The wife couldn't hold back when she saw the report.
It was as if she had endured for many years and finally could release her emotions.
The mother-in-law saw this scene and understood.
