An elderly man and a young man were selling apples on opposite sides of a large tree. The old man's apples were large and red, whereas the young man's looked appealing, though many contained wormholes. Because the prices were identical and the old man had a kind face, customers gradually flocked to his stall. To sell more apples, the young man lowered his price and rearranged his stock, displaying only the best side to customers, which indeed attracted many more. After finishing their business, the two took a ferry home together, and the young man again attempted to take advantage of the old man. The ferry was struck by a sudden wave, causing the two men and the boatman to fall into the water. The old man, finding his money bag too heavy, threw it away, but the young man, seeing this, risked his life to retrieve it.
