Chapter I: I walk down a street. There is a deep hole in the sidewalk. I don't see it. I fall in. It takes forever to find a way out.

Chapter II: I walk down the same street. There is a deep hole in the sidewalk. I pretend I don't see it. I fall in again. I can't believe I am in the same place. But it isn't my fault. It still takes a long time to get out.

Chapter III: I walk down the same street. There is a deep hole in the sidewalk. I see it there. I fall in. It's a habit. BUT my eyes are open. I know where I am. It is my fault. I get out immediately.

Chapter IV: I walk down the same street. There is a deep hole in the sidewalk. I walk around it.

Chapter V: I walk down a different street!

And so it is.
