‘But as his friend Jaime Sabartes recalled, his trusty pocket notebook remained his companion:
“Picasso was endeavoring to recapture the simplicity of our life as young men, despite the manifold and profound changes in us and around us. He wanted to return to a bygone period in our lives. He neither painted nor sketched and never went up to his studio except when it was absolutely necessary, and even then he put it off from day to day, no matter how urgent. In order to occupy his imagination, he wrote-with a pen if he found one handy, or a small stub of pencil-in a little notebook which he carried about with him in his pocket. He wrote everywhere.” ’
