One day, Lucky Dog played with Brave Dog in the park. They rowed boats. They rode bikes. They flew kites. Later, they were tired. They had a rest near the lake. There, they met a cat. They said hello to each other. Then, the cat found a fish behind the dogs. The cat asked the dogs, “Lucky Dog, is this your fish?” Lucky Dog said no. The cat asked Brave Dog, “Brave Dog, is this your fish?” Brave Dog said no. The cat said, “Oh, it’s not your fish. No dogs like fish. So, it’s my fish now! Hmmm, yummy!” The dogs laughed, “All cats like fish.”
