One day, a child found a smooth rock. He liked it a lot. He wanted to lift it and take it home. But, the rock was too heavy for him. He tried and tried, but he could not lift it.
He asked his friend, a big dog, to help him. The dog tried to lift the rock too, but it was too heavy for the dog as well. The child was sad. He did not want to leave the smooth rock.
Then, a kind bird saw the child and the dog. The bird wanted to help them. The bird found a stick and told the child and the dog to lift the rock together. They tried again, and this time, they could lift the smooth rock with the help of the stick. The child was very happy. He thanked the bird and the dog, and took the smooth rock home.
