Suddenly, it started to rain, so they decided to go back home. As they were leaving, they saw a man with a crown and a robe standing outside the cafe. He looked like King Edward, but he was actually a street performer who liked to imitate royalty. He waved at them and said, “Hello, PC Richard! I will come and see you next year!” They smiled and waved back, thinking he was just a harmless eccentric. Just then, they saw the milkman climbing up a ladder that was leaning against a building. He was trying to rescue a cat that was stuck on the roof. They cheered him on and wished him good luck.
