      On one summer day last year, I traveled to a city in France in my car. It was late in the afternoon. I had

booked a room in the Garden Hotel. But I couldn't find the way to it. When I drove along a street, I saw a

beautiful young lady with a lot of bags just coming out of a supermarket. I stopped and asked her, " Excuse me,

Miss. Can you tell me the way to the Garden Hotel? "

      " The Garden Hotel? Certainly. But it may be difficult for you to find it now. I will show you the way if you

like."

      " Oh, thank you so much. Please get into my car." 

      Then I helped her put the bags into the back seats. About three minutes later we came to a two-story

building, the young lady said, " Please stop here."

      I stopped and looked at the building. " But this is not a hotel," I said to her.

      " No," she answered with a smile, " this is my house. And now let me show you the way to the Garden

Hotel. Go along the street and take the first turning on the right. Then you will easily find the Garden Hotel on

your left. It's only a two-minute drive from here. And thank you, Sir, for driving me home." 

      Then, she took up all her bags and walked into her house.
