In the transition from the Chilean social outbreak to the installation of the coronavirus, the philosopher Aïcha Liviana Messina and the psychoanalyst Constanza Michelson establish a crude, tender and honest correspondence, which shuns all doxa or militancy. Their exchanges mix everyday stories, political and social observations, insights on shared books and films, personal memories, disturbing questions, and deep reflections on almost everything: time, family, fear, ethics, illness, landscape, pain. , gambling, insomnia, desire, violence, death, motherhood and childhood. I repeat childhood, that here is the scene of the eternal return. Before the reader (voyeuristic?), The book displays a deep friendship between two women who throw themselves into language, composing, on the edge of this world, another world. With moving rhythms and intensities, an emancipatory dialogue of thought that is also, for the reader, a (not mechanical) respirator.
