210. THE GOATHERD AND THE GOAT
A Goatherd was one day gathering his flock to return to the fold, when one of his goats strayed and refused to join the rest. He tried for a long time to get her to return by calling and whistling to her, but the Goat took no notice of him at all; so at last he threw a stone at her and broke one of her horns. In dismay, he begged her not to tell his master: but she replied, "You silly fellow, my horn would cry aloud even if I held my tongue."
It's no use trying to hide what can't be hidden.
