Once upon a time, there was a big dog named Max. Max had a job to do. He had to work hard every day. He had to help the doctor with an operation. Max was very anxious. He wanted to do a good job.
One day, Max went to work with the doctor. The doctor said, "Max, you must help me with this operation. We need to make the sick cat feel better." Max nodded and tried to help the doctor. He held the tools for the doctor and watched him work.
But Max was too anxious. He dropped the tools and they fell on the floor. The doctor looked at Max and said, "Oh no, Max! We can't finish the operation now. The cat won't get better." Max felt very sad. He knew he had not done a good job.
Max went home that day feeling very bad. He knew that he had let the doctor and the cat down. The cat did not get better, and Max was very sad. He wished he could have done a better job, but it was too late. The cat stayed sick, and Max felt like he had failed.
