SOMETHING has happened to me: I can't doubt that any more. It came as an illness does, not like an ordinary certainty, not like anything obvious. It installed itself cunningly, little by little; I felt a little strange, a little awkward, and that was all. Once it was established, it didn't move any more, it lay low and I was able to persuade myself that there was nothing wrong with me, that it was a false alarm. And now it has started blossoming.
