The story of the angel

It is told that once a young man was walking through an unknown city, when he suddenly came across a store whose façade said on the sign on the signboard: Happiness.

As he entered, he discovered that the people behind the counters were angels. And half startled, he went up to one of them and asked, "Please, what are you selling here?"

"Here? -said the angel- We really do sell everything here."

"Ah, -said the young man astonished-. Will that give me the end of all wars in the world; a great amount of love between people; a great can of understanding between families; more time for parents to play with their children?"

And so he went on until the angel, very reverently, interrupted him and said, "Excuse me, sir. I don't think I explained myself very well. We don't sell fruit here, we sell seeds."
