It was a stormy day, and the snow was falling fast, when a Goatherd drove his Goats, all white with snow, into a desert cave for shelter. There he found that a herd of Wild Goats, more numerous and larger than his own, had already taken possession. So, thinking to secure them all, he left his own Goats to take care of themselves, and threw the branches which he had brought for them to the Wild Goats to browse on. But when the weather cleared up, he found his own Goats had perished from hunger, while the Wild Goats were off and away to the hills and woods. So the Goatherd returned a laughing-stock to his neighbors, having failed to gain the Wild Goats, and having lost his own.
They who neglect their old friends for the sake of new ones, are rightly served if they lose both.
