Last Sunday I went bike riding alone in the countryside.At noon,I was tired and hungry,so I stopped in front of a village inn（小旅馆） and went into it to have something to eat.After I had lunch,I found that my handbag was gone.I had put it on the chair next to me and now it wasn't there!While I was looking for it,the inn-keeper（店主）came up.
"Did you have a good meal?" he asked．
　　"Yes,thank you,"I answered．But I can't pay the bill（账单）．Someone took my handbag．" The inn-keeper smiled and went out right away．A few minutes later he came back with my handbag and gave it to me．
"I am very sorry,"he said．"My dog took it to the garden．He often does this．"
