On the bookmark the author wrote: "I say that a normal and healthy person does not write, but that writing is the only way he can conquer something he cannot really conquer. What I have ever written has always been a victory over something like that. I go on to say that no book works without a female character: she makes the crisis. These entries were written in a different way: from an impulse in the editorial office of the Literary Newspaper, for which I originally intended them. But then I saw it as an opportunity to write something that nothing outside was forcing me to write. But since no book works without a female character, I approached her piano sostenuto."
