One day, a big, loud dog named Max went for a walk. He liked to march on the street with his big feet. Every time he walked, his heels went up and down, up and down. He was so happy when he marched. As Max marched, he saw a little cat. The cat was scared of Max because he was so loud. But Max just wanted to be friends. He stopped marching and said, "Hello, little cat. Let's be friends." The little cat saw that Max was nice. They became friends and marched together. They were happy to march with their heels up and down, up and down. They had fun being loud and making new friends.
