With this book in my hands, reading aloud to my friends, questioning them, explaining to them, I was made clearly to understand that I had no friends, that I was alone in the world. Because in not understanding the meaning of the words, neither I nor my friends, one thing became very clear and that was that there were ways of not understanding and that the difference between the non-understanding of one individual and the non-understanding of another created a world of terra firma even more solid than differences of understanding.
