What should a husband and wife do when they quarrel and see a joke next door?

When a husband and wife quarrel, outsiders will say that such a person is unreliable. You don't have to refute him or pay attention to him. If you ignore him, he will be boring. It is normal for couples not to quarrel in life. It is immoral to say that human nature is inferior to human beings, because no one is perfect and everyone has advantages and disadvantages. How would you feel if it were reversed? So don't refute such people.
