[伊索寓言] 老妪与医师

The Old Woman and the Physician

An old woman, who had become blind, called in a physician and promised him before witness that she would reward him most generously if he could restore her eyesight.  However, he was to receive nothing if he did not cure her malady(疾病)...he finally set about his task in earnest and cured her, whereupon he requested his reward.  But, when the old woman recovered her sight, she saw that her house had been ransacked(洗劫) and continually put off(推迟) the physician with excuses whenever he demanded payment.  Consequently, he summoned(召唤) her before the judges and charged(判罪) her with neglect of payment...

He who plays a trick must be prepared to pay the consequences.
