Virginia Woolf’s diaries are almost obsessively preoccupied with her servants and the challenge of maintaining patience with them. Of one, she writes: “She is in a state of nature: untrained; uneducated … so that one sees a human mind wriggling undressed.” As a class they were as irritating as “kitchen flies.” Woolf’s contemporary Edna St. Vincent Millay was rather more blunt: “The only people I really hate are servants. They are not really human beings at all.”
