There is a boss downstairs who sells industrial lubricants.

His wife has never worked a day in her life. At fifty, she was persuaded by a few divorced sisters who sell insurance to also go to work "to realize personal value."
What does working mean? Selling insurance. Relying on her husband's reputation, everyone bought a policy, and surprisingly, she sold quite well.
The essence of the insurance business is social networking. Within less than a year, she started demanding a divorce.
Their daughter is also clueless, raised entirely by her mother, who always listened to her, and surprisingly, she supported her parents' divorce.
After the divorce, they found out that sales of insurance had completely dried up, and they suddenly lost their source of income.
Thinking about remarriage? Everyone knows the situation of women in the insurance circle. She’s already in her fifties; who would want her?
In the end, she could only move back to the countryside to live with her eighty-something parents.
As for the man, he quickly remarried a college girl in her twenties, and like a late-blooming flower, he also had a pair of twin sons.
This time, the boss really made a big profit: the nagging wife is gone, the new wife is young and beautiful, and she even gave birth to a son. The billions in family assets finally no longer need to worry about being handed over to the son-in-law.
