• "I suppose this goes to show that, from an anthropological point of view, the truly interesting part of any human encounter is its beginning. I can instantly identify friends and colleagues from the rhythm of their knock at the door, or the slight pause before they identify themselves on the phone – those tiny gestural and auditory signatures, both idiosyncratic and culturally produced, that make us human." Greetings and openings, principally, to do with telephones.
