The Labourer and the Nightingale
"We Nightingales never sing in a cage." said the bird. "Then I'll eat thee." said the Labourer. "I have always heard say that a nightingale on toast is dainty morsel." "Nay, kill me not," said the Nightingale; "but let me free, and I'll tell thee three things far better worth than my poor body." The Labourer let him loose, and he flew up to a branch of a tree and said: "Never believe a captive's promise; that's one thing. Then again: Keep what you have. And third piece of advice is: Sorrow not over what is lost forever." Then the song-bird flew away.
