"I studied art there in the late 1950s for two semesters before I started to write. I was in Mexico City...It was an important experience in my life...For the first time...I saw that art could make strong political and social statements. It didn't have to be only poster art or cheap propaganda; it didn't have to be slogans, it could be very deep, it could be adapted to everyday life, to everything you do in your life."
