"NETTEZZA URBANA..." "DEPARTMENT OF SANITATION" "Over the course of a day, we encounter so many people and things and activities that seem familiar and routine but which we actually know little about... only the little that directly affects our own lives." "Everything else is foreign to us." "Who are these street cleaners, and how do they live, these silent, humble workers that no one even speaks to or looks at?" "It hardly seems our concern." "They seem like some inanimate part of the city, and yet no one shares in the life of the city more." "How do they see that life?" "Their work begins long before the city wakes."
