Ever since I read the excellent La vie, mode d'emploi, I've been an admirer f Georges Perec, and even since no other of his books has appealed as much to me, I have liked all I've read by him. Un homme qui dort is very good, extremely insightful in what concerns the existential disenchantment with the world, a feeling we could call depression, but somehow if feels like is something simultaneous more and less than that, more a state of mind than a medical condition. And he writes in such a beautiful French! At the end, a sentence stuck in my mind: L'indifférence ne t'a pas rendu indifférent. He got it.
