Have a Guess 

I looked at the world outside the window, and start to observe what happened there. Walking passers-by, Where did he come from and where did he go? In every window of the opposite flat, What kind of world are they? The endless stream of trains, Where will it take me? If you ask where I am, I will answer you that I am in London. But is this true? Just have a guess. The world doesn't make sense anyway.
