The Little Prince (9786059913720)

"So when you look at the sky at night, it will be as if all the stars were laughing; as though in one of the stars I live and I will be laughing You will have stars that know how to laugh!"

And he laughed again.

"And when your sorrow is comforted (with time all sorrows pass) you will be glad that you have known me. You will always be my friend. You will want to laugh with me. And you will open your window, and your friends will be surprised to see you laughing as you look up at the sky! Then you will say to them, 'Yes, the stars always make me laugh!' And they will think you are crazy. It will be my little joke that I will have played on you"
