Ingratitude sometimes brings its own punishment.恩将仇报有时会受到更严重的惩罚
 
A Stag, pursued by the huntsmen, concealed himself under cover of a thick Vine. They lost track of him and passed by his hiding-place without being aware that he was anywhere near. Supposing all danger to be over, he presently began to browse on the leaves of the Vine. The movement drew the attention of the returning huntsmen, and one of them, supposing some animal to be hidden there, shout an arrow at a venture into the foliage. The unlucky Stag was pierced to the heart, and, as he expired, he said, “I deserve my fate for my treachery in feeding upon the leaves of my protector.”

 　　一只鹿为了逃避猎人的追捕，躲藏在一棵茂盛的葡萄藤下，猎人找不到鹿的踪迹了，虽然刚从葡萄藤旁边经过，却并没有发现他。鹿以为躲过了危险，便旁若无人地开始吃那茂盛的葡萄叶子。这个动作引起了猎人们的注意，他们马上调回头来，其中一个人认为叶子底下一定躲着什么动物看，一箭就射中了鹿。不幸的鹿被刺穿了心脏，临死前说道：“我真的活该，因为我恩将仇报，吃了那曾经救过我一命的葡萄藤。”
