The Fox And The Hedgehog
Fox, in swimming across a rapid river, was swept away by the current and carried a long way downstream in spite of his struggles, until at last, bruised and exhausted, he managed to scramble on to dry ground from a backwater.
As he lay there unable to move, a swarm of horseflies settled on him and sucked his blood undisturbed, for he was too weak even to shake them off.
A Hedgehog saw him, and asked if he should brush away the flies that were tormenting him.
The Fox replied, "Oh, please, no, not on any account, for these flies have sucked their fill and are taking very little from me now; but, if you drive them off, another swarm of hungry ones will come and suck all the blood I have left, and leave me without a drop in my veins."
