Once upon a time, there was a little rocket. The rocket wanted to fly high in the sky. It said, "I hope I can be successful and go up, up, up!"
One day, the rocket met a big bird. The bird said, "I can help you fly high in the sky." The rocket was happy and said, "Yes, please help me!"
The bird tried to help the rocket. They went up, up, up together. But then, the rocket was too heavy for the bird. The bird could not fly anymore. They both fell down, down, down.
The rocket was sad. It said, "I am not successful. I cannot fly high in the sky." The bird was sad too. They both did not get what they wanted.
