Fox and Crow

Some time ago, Fox was walking when he noticed crow  up on a bough, happily chewing a piece of cheese. 

  "Good day, Lady Crow," he said, "How well you are looking today.”
Crow, though her mouth was full, nodded her head politely. Fox smiled. “ And you are looking quite nice. How glossy your feathers, how bright your eye. And your voice as you fly over; I feel sure your voice must surpass that of other birds, just as your figure does.”
Crow preened proudly.
“Oh please, dear lady,” called Fox, “ let me hear a single song from your perfect beak."
     The Crow lifted her head and began to caw her best, but as she opened her mouth the piece of cheese fell to the ground, to be snapped up by Fox.
     "Very good," said he. "And in exchange for your cheese I will give you a piece of advice: do not trust flatterers."
