"Good morning," said the merchant.

"Why are you selling those?" asked the little prince.

"Because they save a tremendous amount of time," said the merchant. "Computations have been made by experts. With these pills, you save fifty-three minutes in every week."

"Anything you like…"

"And what do I do with those fifty-three minutes?"

This was a merchant who sold pills that had been invented to quench thirst. You need only swallow one pill a week, and you would feel no need of anything to drink.

"As for me," said the little prince to himself, "if I had fifty-three minutes to spend as I liked, I should walk at my leisure toward a spring of fresh water."
