      When Mr David retired (退休), he bought a small house in a village near the sea. He liked it and hoped to live

a quiet life in it.

      But to his great surprise, many tourists came to see his house in summer holidays, for it was the most

interesting building in the village. From morning to night there were tourists outside the house. They kept looking

into the rooms through the windows and many of them even went into Mr David's garden. This was too much

for Mr David. He decided to drive the visitors away. So he put a notice on the window. The notice said: "If you

want to satisfy your curiosity (好奇心), came in and look round. Price: twenty dollars." Mr David was sure that

the visitors would stop coming, but he was wrong. More and more visitors came and Mr David had to spend

every day showing them around his house. "I came here to retire, not to work as a guide." he said angrily. In the

end, he sold the house and moved away.
