" So. There are a great many things. I am trying to tell them to you. I know that all is not right in my head. And it is true, yes, and I say this of my own free will, that sometimes I just scream and scream. For no good reason. As if there had to be a reason. But for none that I can see. Or anyone else. No. And then there are the times when I say nothing. For days and days on end. Nothing, nothing, nothing. I forget how to make the words come out of my mouth. Then it is hard for me to move. Ya ya. Or even to see. That is when I become Mr. Sad. "

― Paul Auster , City of Glass (The New York Trilogy, #1)
