at one time the horse had the plain entirely to himself. then a stag intruded into his domain and shared his pasture. the horse, desiring to revenge himself on the stranger, asked a man if he were willing to help him in punishing the stag. the man replied that if the horse would receive a bit in his mouth and agree to carry him, he would contrive effective weapons against the stag. the horse consented and allowed the man to mount him. from that hour he found that instead of obtaining revenge on the stag, he had enslaved himself to the service of man.

曾经有一段时间，马过着舒适、安稳的生活。【[快穿]拿下那個絕世反派】可是，有一天，马这样的生活被打断了，因为有一只雄鹿过来要和他一起分享一块草地。马想赶走这个讨厌的入侵者，就向人寻求帮助，问人是否愿意帮助他把雄鹿赶走。人答应了马，但是提出了一个条件:如果他成功把雄鹿赶走，就要在马的嘴上放一件东西。一心想达到目的的马爽快地答应了人的条件。当人骑上他的后背之后，满怀希望的马才意识到自己的处境:把雄鹿赶走是奢望，因为带上嚼子的自己已经沦为人的奴隶。

你在要求别人帮助你达到目的的时候，别人也会要求你这样做的。
