There are four things in life: helping mud, carving rotten wood, turning salted fish and scalding dead pigs. When the mud is lying down, people should be helped to the wall. When the rotten wood is rotten, it should be carved into talents. When the salted fish is lying down, it should be turned over. When the dead pig dies, it will burn people. Everyone's life is different. Don't impose your set of values on others. Dickens said that the best manners are to mind your own business.
