The Ass and His Purchaser

A man wished to purchase an ass, and agreed with his owner that he should try him before he bought him. He took the ass home and put him in the straw-yard with the other asses, upon which he left all the others and joined himself at once to the idlest and the greatest eater of them all. The man put a halter on him and led him back to his owner; and on his inquiring how, in so short a time, he could have made a trial of him, "I do not need," he answered, "a trial; I know that he will be just such another as the one whom of all the rest he chose for his companion."

A man is known by the company he keeps.
