A man wished to purchase an Ass, and agreed with its owner that
he should try out the animal before he bought him. He took the Ass
home and put him in the straw-yard with his other Asses, upon
which the new animal left all the others and at once joined the one
that was most idle and the greatest eater of them all. Seeing this,
the man put a halter on him and led him back to his owner. On
being asked how, in so short a time, he could have made a trial of
him, he answered, "I do not need a trial; I know that he will be just
the same as the one he chose for his companion."
A man is known by the company he keeps.
