Aesop for Children (1919)
136. THE SWALLOW AND THE CROW
The Swallow and the Crow had an argument one day about their plumage.
Said the Swallow: "Just look at my bright and downy feathers. Your black stiff quills are not worth having. Why don't you dress better? Show a little pride!"
"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."
Friends in fine weather only, are not worth much.
