I have visited a place many times but I may still get lost there the next time. When I was a little girl, I never dared ask strangers the way. And so I used to walk round in circle and hope that by chance I would get to the place I was going to. Now , I am no longer too shy to ask people for directions, but I often receive helpless or even wrong information. So I try to avoid giving people wrong directions. If anyone asks me the way somewhere, I would say,sorry, I am a stranger here. Once on my way to work I was stopped by a man. He asked me if I could tell him the way to the Friendship Building. I gave him my usual reply. But just as I walked on only a few steps. I realized that he had asked the way to my office building. However, I had no time to turn back and look for him.
