Once upon a time, in a small town, there lived a human named Tom. Tom was a kind man who had a dog named Max. They were best friends and played together every day. One day, Tom had to send a letter to his friend who lived far away, but he was frustrated because he didn't know how to send it.
Tom asked Max for help. Max was a smart dog and knew what to do. Max took the letter in his mouth and ran to the post office. The postman saw Max and took the letter from him. The postman smiled and said, "Thank you, Max! You are a very helpful dog."
Tom was so happy when he found out that Max had sent the letter. He hugged Max and said, "You are the best friend a human could have!" From that day on, Tom and Max learned that they could always help each other when they were frustrated. And they lived happily ever after.
The moral of the story is: always help your friends when they need you, and never give up when you are frustrated.
