The Wolf and the Crane 狼与鹭鸶

The Wolf and the Crane狼与鹭鸶 

A WOLF who had a bone stuck in his throat hired a Crane, for a large sum, to put her head into his mouth and draw out the bone. When the Crane had extracted the bone and demanded the promised payment, the Wolf, grinning and grinding his teeth, exclaimed: "Why, you have surely already had a sufficient recompense, in having been permitted to draw out your head in safety from the mouth and jaws of a wolf." 

In serving the wicked, expect no reward, and be thankful if you escape injury for your pains. 狼误吞下了一块骨头，十分难受，四处奔走，寻访医生。他遇见了鹭鸶，谈定酬金请他取出骨头，鹭鸶把自己的头伸进狼的喉咙里，叼出了骨头，便向狼要定好的酬金。狼回答说：“喂，朋友，你能从狼嘴里平安无事地收回头来，难道还不满足，怎么还要讲报酬？” 

这故事说明，对坏人行善的报酬，就是认识坏人不讲信用的本质。
