Goodbyes and all that!

What must I do, to tame you?
asked the little prince.

"You must be very patient," replied the fox.
First you will sit down
at a little distance from me
-like that-in the grass.
I shall look at you out of the corner of my eye,
and you will say nothing.
Words are the source of misunderstandings.
But you will sit a little closer to me,
every day..."

...................
And he went back to meet the fox.
"Goodbye" he said.

"Goodbye," said the fox.
"And now here is my secret, a very simple secret:
It is only with the heart that one can see rightly;
what is essential is invisible to the eye."
