The Little Prince - Antoine de Saint-Exupéry

"It would have been better to come back at the same hour," said the fox. "If, for example, you come at four o'clock in the afternoon, then at three o'clock I shall begin to be happy. I shall feel happier and happier as the hour advances. At four o'clock, I shall already be worrying and jumping about. I shall show you how happy I am!"
