“So the little prince tamed the fox. And when the time for him to leave was approaching: "Oh!", said the fox. "I am going to cry." "It's your own fault," said the little prince. "I never wished you any harm; but you wanted me to tame you..." "I know," said the fox. "And now you're going to cry!" said the little prince. "I know," said the fox. "So you have gained nothing from it at all!" "Yes, I have gained something," said the fox, "because of the colour of the corn.”
