Isabella was visiting Spain for the first time. While ordering food at a restaurant, she wanted to ask for fish, but she accidentally asked for "pez," which means the pet fish, not food. The waiter looked confused but smiled. He explained the difference between "pez" and "pescado." Isabella laughed and thanked him. Later, she shared the funny story with her friends back home. “I’ll never forget that mistake,” she said. It reminded her that learning a language is full of small, funny lessons.
