He knocked at the door, and the writer by chance opened it himself. “here”, said the boy, “my master has sent you a basket full of things”. Swift, feeling displeased at the boy’s rude manner, said to him: “Come here, my boy, and I will teach you how to deliver a massage 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 send 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.
