Let me put it this way. I’m only inventing what I can positively recall. If it is something I remember, then I write it down. I don’t write it unless I can definitely remember it. But once I start to write it down, I must needs invent it, in terms of how it happened. If I write it down, it happened, but not necessarily how I write it. What I write down didn’t happen, but it didn’t happen less than all the things I don’t write down, which didn’t happen at all.
