One day, a big dog named Max and a small cat named Lily were playing in the park. Max was very strong and had big muscles. Lily was small but she was very fast. They liked to play together even though it was sometimes difficult for Lily to keep up with Max.
Max said to Lily, "Let's play a game of catch. I will throw the ball and you try to catch it." Lily was scared because Max threw the ball very far. But she did not want to refuse the game. So, she said, "Okay, let's play!"
Max threw the ball far, far away. Lily ran as fast as she could to catch the ball. It was difficult, but she did not give up. She used all her muscles to jump and catch the ball. Max was very happy and said, "Good job, Lily! You are very strong and fast!"
Lily was very proud of herself. She learned that even if something is difficult, she should not refuse to try. Max and Lily played more games and had a lot of fun together.
