And I will make you a present of a secret

So the little prince tamed the fox. And when the hour of his departure drew near - "Ah," said the fox, "I shall cry."
"It is your own fault," said the little prince. "I never wished you any sort of harm; but you wanted me to tame you..."
"Yes, that is so," said the fox.

"But now you are going to cry!" said the little prince.
"Yes, that is so," said the fox.
"Then it has done you no good at all!"
"It has done me good," said the fox, "because of the colour of the wheat fields." And then he added:
"Go and look again at the roses. You will understand now that yours is unique in all the world. Then come back to say goodbye to me, and I will make you a present of a secret."

The little prince went away, to look at the roses.
"You are not at all like my rose," he said. "As yet you are nothing. No one has tamed you, and you have tamed no one. You are like my fox when I first knew him. He was only a fox like a hundred thousand other foxes. But I have made him my friend, and now he is unique in all the world."
And the roses were very much embarrassed.

"You are beautiful but you are empty," he went on. "One could not die for you. To be sure, an ordinary passerby would think that my rose looked just like you - the rose that belongs to me. But in herself alone she is more important than all the hundreds of you other roses: because it is she that I have watered; because it is she that I have put under the glass globe; because it is for her that I have killed the caterpillars (except for the two or three that we saved to become butterflies); because it is she that I have listened to when she grumbled, or boasted, or even sometimes when she said nothing. Because she is my rose."
