Once there was a wise old man. He could answer any question in the world. Everybody knew about him. One day two boys said: « We are going to fool that old man. `We`ll catch a bird, go to the old man and say, We are holding something in our hands. Is it alive or is it dead?` If he says, `Dead`, we`ll let the bird fly, and if he says, ` Alive,` we`ll kill it.»

They caught a bird and they carried it to the old man and they said, « We are holding something in our hands. Is it alive or is it dead?» And the wise old man looked at the young people and smiled. « It`s in your hands,» he said.
