Once upon a time, there was a big dog. His name was Max. Max was very hungry. He saw a bone on the ground. He wanted to eat it. But there was a small cat there too. The cat did not want Max to eat the bone. Max tried to bite the cat. But the cat was too fast. The cat ran away. Max was sad. He still wanted the bone. He tried to get it with his mouth. But he could not. Then Max saw something shiny. It was a zipper on a bag. The bag was very large. Max had an idea. He could open the bag with the zipper. Maybe there was food inside. Max tried to open the zipper. It was hard. But he did it. Inside the bag, there was a big steak! Max was so happy. He ate the steak and forgot about the bone. He was full and happy. The cat came back and saw Max eating. The cat was not mad anymore. They became friends and played together. The end.
