     I was in a strange city I didn't know at all, and what's more, I could not speak a word of the language. On my second day I got on the first bus that passed, rode on it for several stops, then got off and walked

on. The first two hours passed pleasantly enough, then I decided to turn back to my hotel for lunch. After walking about for some time, I decided I had better ask the way. The trouble was that the only word I

knew of the language was the name of the street in which I lived, and even that I pronounced badly. I

stopped to ask a newspaper-seller. He handed me a paper. I shook my head and repeated the name of

the street and he put the paper into my hands. I had to give him some money and went on my way. The

next person. I asked was a policeman. He listened to me carefully, nodded and gently took me by the

arm. There was a strange look in his eyes as he pointed left and right and left again. I nodded politely and

began walking in the direction he pointed.?

     About an hour passed and I noticed that the houses were getting fewer and fewer and green fields

were appearing on either side of me. I had come all the way into the countryside. The only thing left for

me to do was find the nearest railway station.
