Why do many close relationships not all stem from unreasonable behavior when disagreements occur? In fact, it is often through unreasonable behavior that interests are fought for. Humans naturally understand: discussing interests is very dangerous, while discussing principles is safer. If you directly say: I want to obtain more resources. The other party will definitely be on alert. But if you say: I am the one who is right. Then, the struggle for interests can be disguised as moral judgment. Therefore, a mature person, when viewing conflicts in close relationships, will see two layers at the same time: the surface layer is what both parties are saying about principles, and the deeper layer is what both parties are trying to gain—interests, power, and status.
