The Donkey and the Tiger
The donkey told the tiger: ′′The grass is blue".
The tiger replied: ′′No, the grass is green".
The discussion became heated, and the two decided to submit the issue to the lion, King of the Jungle.
Before reaching the clearing in the forest where the lion was sitting on his throne, the donkey started braying: ′′Your Highness, is it true that grass is blue?".
The lion replied: "True, the grass is blue".
The donkey rushed forward and continued: ′′The tiger disagrees with me and contradicts me and annoys me please punish him".
The king then declared: ′′The tiger will be punished with 5 years of silence".
The donkey jumped for joy and went on his way, content and repeating: ′′The grass is blue"...
The tiger accepted his punishment, but he asked the lion: ′′Your Majesty, why have you punished me, after all, the grass is green?"
The lion replied: ′′In fact, the grass is green".
The tiger asked: ′′So why do you punish me?"
The lion replied: ′′The punishment has nothing to do with the question of whether the grass is blue or green. The punishment is because you, a brave, intelligent creature, waste time arguing with a donkey, and then come and bother me with a silly question".
The moral of the story is, teach those who are willing to learn, rather than bickering with those who aren't.
