The two robins

One day a robin finds a paper bag.He pecks it open."there is a bun inside," he says happily.A second robin comes along. He pecks at the bun."It is mine"! he says.The two robins quarrel over the bun.A crow hears them ."Whats the matter?" he asks.They tell him everything.The crow says,"I will give this bun that sings better.Now,turn around and start singing.They until they are tired.Then they look around.The crow is not there.The paper bag with the bun is not there,too."Next time we shall just share what we find!" says the first robin. They are both very sad.
