When Saya sends a text to tell me she has a new boyfriend, I instantly write back: What’s he like? But all she replies is: He’s a doctor. Nothing about looks or personality, or what kind of doctor he is—I mean, he could be any kind, couldn’t he? It’s true I know what she means by doctor. Jobs can be a clue to somebody’s character. A short-cut way of describing them. But only in a limited, stereotyped sort of way.
