The Hares and the Frogs explained simply

The Hares once gathered together and lamented the unhappiness of their lot, exposed as they were to dangers on all sides and lacking the strength and the courage to hold their own. Men, dogs, birds and beasts of prey were all their enemies, and killed and devoured them daily: and sooner than endure such persecution any longer, they one and all determined to end their miserable lives. Thus resolved and desperate, they rushed in a body towards a neighbouring pool, intending to drown themselves. On the bank were sitting a number of Frogs, who, when they heard the noise of the Hares as they ran, with one accord leaped into the water and hid themselves in the depths. Then one of the older Hares who was wiser than the rest cried out to his companions, "Stop, my friends, take heart; don't let us destroy ourselves after all: see, here are creatures who are afraid of us, and who must, therefore, be still more timid than ourselves."
