Once upon a time, there was a boy named Mark. He had a dog named Spot. They loved to play together. One day, they went to the park to play. They saw a big tree and decided to play near it.
A bird was in the tree. The bird was making a crazy sound. Mark said to Spot, "Do not disturb the bird." But Spot did not listen. He barked at the bird. The bird got scared and flew away.
Mark was sad. He told Spot, "We should not disturb others when they are happy." Spot understood and promised not to disturb anyone again. They played happily in the park and let the bird be. From that day on, Mark and Spot always tried to be kind and not bother others.
