I was waiting on the station platform for the Tianjin train when a man asked me if I knew the time of the next train to Tianjin. I often had to go there myself, so I knew and told him. A few minutes later an old lady wanted to know whether the train to Shanghai had already left. I knew that it had not, So of course, I told her. Then a girl came to me and asked why the train from Nanjing was late. I just told her that when trains were late, it was usually because something had happened. I was wondering why all these people were asking me those questions when I noticed that I was standing next to a sign that said "Inquiry Office."
