Once upon a time, there was a high tree. A robot lived in the tree. The robot had a friend, a little bird. They liked to play together.
One day, the robot tried to fly like the bird. He jumped from the tree. But robots cannot fly, so he began to fall. The bird saw and yelled, "Robot, be careful!"
The bird flew fast to help the robot. The bird caught the robot before he hit the ground. The robot said, "Thank you, bird!" They were happy and played more games on the ground.
