People did not know what she knew, that she was not really a woman but a man, often a fat man, but more often, probably, an old man. The fact that she was an old man made it hard for her to be a young woman. It was hard for her to talk to a young man, for instance, though the young man was clearly interested in her. She had to ask herself, Why is this young man flirting with this old man?
