Joe Smith is a singer. He and his wife like traveling a lot. Every year they visit a small town called Gum Tree in January and July and sing for people there.
One summer, they went there by train again. On the first day, they planned to go hiking in the mountains, but it rained a lot. So they decided to go to the only cinema in town and watch a movie.
There were only nine people in the cinema hall. When people saw the Smiths, they started clapping. Joe was excited and said to his wife, "Aha, I can't believe people here all know me and they are friendlier than I thought. They must like my songs."
Then a young man said to them, "Thanks for your coming! The cinema shows the movie only after ten people buy the tickets. There are eleven now, so the movie will be on soon."
