some boys, playing near a pond, saw a number of frogs in the water and began to pelt them with stones. they killed several of them, when one of the frogs, lifting his head out of the water, cried out: "pray stop, my boys: what is sport to you, is death to us."

一些孩子在池塘边玩耍，看到了池塘里的青蛙后，就把石头扔向他们，并以此为乐。伤亡惨重的青蛙向孩子们哭诉:“求求你们，不要这么做了，你们是在愉快地玩耍，我们却要付出生命的代价。”

不要把自己的快乐建立在别人的痛苦上。
