"(You, as a person, in the context of the world today, do you feel like part of society, or do you feel solitary?) CL: Well, I have friends, friendships, but writing is a solitary act. Outside the act of writing, I get along with people. (So you don’t feel solitude?) CL: Sometimes, sometimes, even quite deeply. Alceu Amoroso Lima wrote something that’s been repeated a lot, that I was in a tragic solitude in Brazilian letters."
