A man wanted to get married, so he went to his uncle. He said to him, “Uncle, you have been married for years, and you have never quarreled with your wife, so what is the secret?” His uncle said, “My wife and I agreed from the first day that she would give her opinion on small problems, and I would give my opinion on big problems.” He said, “Uncle, I don’t understand you?!” He said, “Listen, for example, my wife has the authority to buy the house, arrange the furniture, paint the rooms,
the type of flowers in the garden, what we eat and drink, raise the children, dispose of my salary, where we spend our vacations, who we visit, with whom we build a social relationship, with whom we quarrel, and even what we watch on TV, etc.” He said to his uncle, “Excuse me, uncle, but what do you control then?” The uncle said, “I give my opinion on big and dangerous matters, for example: Sino-American relations, the Russian war in Ukraine, the repercussions of a third world war, climate change, the ozone hole, I mean on big strategic matters. Do you understand me, my nephew?” He said, “Now I understand, you my uncle.”
