Jonathan Swift and the Errand Boy
Jonathan Swift, the famous Irish writer (1667-1745), leading satirist of his age, was not very generous. He seldom gave anything to the servants of those who sent him presents. But once he received a lesson from a boy who very often brought him hares, partridges, and other game.
One day the boy arrived with a heavy basket full of fish, fruit, and game. When Swift opened the door, the boy said gruffly, Here, my master has sent you a basket full of things. Swift, feeling displeased at the boy's rude manners, said to him: Come here, my boy, and I will teach you how to deliver a message a little more politely. Come, imagine yourself Jonathan Swift, and I will be the boy.
Then taking off his hat very politely and addressing himself to the boy, he said: Sir, my master sends you a little present and begs you will do him the honor to accept it.
Oh, very well, my boy, replied the boy, tell your master I am much obliged to him, and there is half a crown for yourself.
Swift laughed heartily, and gave the boy a crown for his wit.
