A walnut fallen on a narrow lane Seemed very nice and tempting, so to speak, That four black crows descended, I maintain, To grab it with their long and pointed beak. But one of them, for sure, had much more luck And took advantage of the stir and fight, And while avoiding to be caught and struck Seized the small nut and hastily took flight. After a while, it flew down to the ground, Because the other crows gave up the chase, Then cracked the nut and baffled looked around, For it was hollow in its inner space. That's why in life I have this wondrous creed, Both husk and core should be refined, indeed.
