How to read the sentence "Good husband and wife during the day, good neighbors at night"?

I think it's better not to read it, because reading it means watching the world of mortals, and it will be very bitter in many cases, so I hope you don't understand it.

What is a good couple during the day and a good neighbor at night? It means that two people are harmonious couples in front of outsiders during the day, giving people the feeling that the feelings of couples seem to be good. In front of friends, neighbors and relatives, the two people showed their good feelings and were very happy, but in the evening, they finally closed the door and stopped acting, so they became strange neighbors.

I hope it won't happen to me in my life. This is the relationship between my friend and her husband. Sometimes I think she is in pain, but I can't divorce because of the children, so sometimes I really sympathize with her. At the age of 30, I still have to put up with this life. How bitter that should be.

This happens because two people don't love each other and have no feelings. They don't even want to say a word in private, and they are stranger than strangers. If possible, I believe they have divorced long ago, but because of the children and many factors, they have to make do.

Of course, when you are dying, it is impossible to fall in love again. At this time, two people are like strangers. For example, my friend is at home, she and her husband are neighbors, and she and her husband are separated. She has a room, one for her children and one for her husband. For example, she doesn't have to go out on weekends and her husband doesn't go out. She plays with her children in the living room and doesn't have to cook for her husband when it's time to eat. Sometimes her husband knows her when she orders takeout.

Except for the children, they hardly contact each other, and it doesn't matter how late they come back, but they usually seem to be more affectionate in front of their relatives. Both of them have reasons not to divorce, but they just don't get along well. This is a couple who got on well during the day and became neighbors at night. They are just neighbors living under the same roof.
