A Heron was walking sedately along the bank of a stream, his eyes on the clear water, and his long neck and pointed bill ready to snap up a likely morsel for his breakfast. Alas, O Jupiter, man does not know what he asks! He walked about restlessly, tearing up the ground with his toes, and beating his arms savagely against his sides. Is this your constancy? she exclaimed tearfully. You laughed when I said I would repay you, said the Mouse. Do not worry about us, replied the Reeds. Such scanty fare is not fit for a Heron. Your feathers may do very well in spring, replied the Crow, but I don't remember ever having seen you around in winter, and that's when I enjoy myself most.
Do not grudge others what you cannot enjoy yourself.
