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 quier lift 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 satify 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 recite , not to work as a guide , ” he said angrily . In the end , he sold the house and moved away .
