A farmer lay listening to a nightingale(夜莺)’s song throughout(在整个期间) one summer night.
He was so pleased with it that the next night he set a trap(陷阱) for it and caught it.
“Now I have caught you,” he cried, “and you will always sing to me.”
“We nightingales(夜莺) never sing in a cage(笼子),” said the bird.
“Then I’ll eat you,” said the farmer.
“I have always heard that a nightingale(夜莺) on toast(吐司) is delicious.”
“No, don’t kill me,” said the nightingale(夜莺); “but set me free, and I’ll tell you three things worth much more than my poor body.”
The farmer let him loose, and he flew up to a branch(树枝) of a tree and said, “Never believe a prisoner(囚犯)’s promise; that’s one thing. Then again: keep what you have. And third piece of advice is: do not waste your sadness on what is lost forever(永远).”
Then the song-bird flew away.
MORAL: If you love someone, set them free.
