Sam visited his grandmother, who lived nearby but they didn't see each other often. She took a long time to answer the door and her house was very clean, like a museum. Sam wonders what "hoovered" means. One day Sam visited his grandmother. She lived close to Sam, but he didn't see her that often. She always took comedically long to come to the door. Her house was perfectly preserved, like a museum. It was always clean and hoovered. Hoovered? What is that?
