The Crow and the Serpent
A Crow, in great want of food, saw a Serpent asleep in a sunny nook, and flying down, greedily seized him. The Serpent, turning about, bit the Crow with a mortal wound. The Crow in the agony of death exclaimed: "O unhappy me! who have found in that which I deemed a most happy windfall the source of my certain destruction."
What seem to be blessings are not always so.
