驴和买驴的人The ass and his purchaser
A man wanted to buy an ass. He went to the market, and saw a likely one. But he wanted to test him first.
So he took the ass home, and put him into the stable with the other asses. The new ass looked around, and immediately went to choose a place next to the laziest ass in the stable.
When the man saw this he put a halter on the ass at once, and gave him back to his owner.
The owner felt quite surprised. He asked the man, “Why are you back so soon? Have you tested him already?” “I don’t want to test him any more,” replied the man, “From the companion he chose for himself, I could see what sort of animal he is.”
