Aesop's Fables (1884)
45. The Boys and the Frogs.
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."
What we do in sport often makes great trouble for others.
