Wood, who grew up in England but has lived in the United States for 18 years, explores a certain form of contemporary homelessness — lives lived without the finality of exile, but also without the familiarity of home.He speaks of existences “marked by a certain provisionality, a structure of departure and return that may not end.”This is a widespread modern condition; perhaps it is the modern condition. Out of it, often, comes anxiety. Wood does not focus on the psychological effects of what he calls “a certain outsider-dom,” but if you dig into people who are depressed you often find that their distress at some level is linked to a sense of not fitting in, an anxiety about belonging: displacement anguish. - www.nytimes.com
