" In the deepest, most unalterable sense, he was an invisible man. Invisible to others, and most likely invisible to himself as well. If, while he was alive, I kept looking for him, kept trying to find the father who was not there, now that he is dead I still feel as though I must go on looking for him. Death has not changed anything. The only difference is that I have run out of time. "

― Paul Auster , The Invention of Solitude
