Any good is no joy if there is no one to share it with. This is called family. When two people live and complement each other. But the most valuable thing in the world is reciprocity. It is the same desire to say or do something for the sake of a person. When you are not afraid to look stupid, because you know that you will not be laughed at and humiliated. When you are you, next to someone who appreciates and respects you.
