In the middle of the dark forest，there lives an owl（猫头鹰）．All the animals know that he is the wisest among all of them．So they often go to him and tell him their problems．Then the owl always teaches them what to do．

One day，a little bird goes up to the owl．She starts crying．

"I'm not happy at all．I don't want to be a bird，" says the bird．

"Why don't you want to be a bird？"asks the owl．

 "I am so small，weak and useless．I want to be big and strong like the lion．He is very important，but I am not，"she cries．

Then the owl whispers（耳语）something in her ear．At once the bird dries her tears and goes away．One week later，the bird comes back．"Oh，thank you very much．You are a very wise owl，"she says to the owl．"I am very happy now．Every day，I sit on the tallest tree and watch for lions and tigers．When they come near，I shout at the top of my voice．Then my friends all run and hide．They are very thankful to me．I am useful and important now．"

The wise owl smiles and says，"No one in this world is useless．"
