Hey, there's a bird singing in the tree!
Once upon a time there was a little bird, singing in the tree, while the rain softly died away. The bird didn't sing for someones benefit, it sang only for its own sake. Its song was as beautiful as a sunset over the sea and everyone who came along the tree, came to an halt and listened carefully. Soon there stood a little crowd, children, men, women, old people and young people. They all stood and listened to the beautiful song, that sounded as if the joy itself had gotten wings and flew above their heads now. And the rain, that has always been there, softly died away. When the birds song faded at last and silence crept over the people standing around the tree, they looked around, saw their faces for the first time and instantly knew that they forgot how to hate each other. They could feel only deep love and joy. The little bird didn't care. It was as happy as ever before and when it flew away, no one noticed. And the bird flew to its nest and fed its children and sang a new song, and it didn't know, that it just ended a never ending war, that it just cured a whole species from the cruelest disease the world has ever seen.
Because the bird was only a little bird, singing its songs in trees, for no ones benefit, only for its own sake.
