Here is a fable:
There was a king, because the king of neighboring countries gave him the best piece of wood, and he ordered a carpenter to help his beloved dog build a house. As a result, the carpenter accidentally broke down, there is no way to find the same wood. The King is very angry and will kill him. He had to go home crying and say goodbye to his wife. After his wife asked the reason, he told him not to be afraid. As long as he told the king, and gave him three years, he would be able to help the king speak to his beloved dog church, the king will not kill him!
He said to his wife, "You're crazy. How can I teach a dog to speak? Even if the king agrees not to kill me for the moment, isn't he still trying to kill me after three years?
His wife said: You think, in the past three years, the King may die, the dog may die, and the worst plan, maybe the dog has to learn to speak?
