What does it mean that parents love each other and children are the other?

"Parents love children is another matter" means: parents love each other and just want to be alone, but I didn't expect to have children later.

I heard my mother say this topic:

My mother and father were introduced. They have a good relationship together. My father supports my mother's work, and my mother supports my father. Dad is an excellent person. He doesn't smoke or drink, and his personality is very docile. Therefore, when they are together, they hardly stumble. I really haven't seen them.

Later, mom and dad chatted together and I eavesdropped. My mother said, "honey, we love each other very much, but children are another matter." Dad was surprised and said, "Why? Don't you feel happy? " Mom said, "Because I really want to be alone with you."

Yes, I know my mother is joking. How can a family have no children? Besides, children are a good link to maintain the relationship between husband and wife.

So, if you hear this sentence, don't take it to heart, which also shows that your parents love each other very much.
