Even though I tend to have a Swiss cheese memory, there are times when at least I recreate something almost verbatim, without even realizing I have done it before. (Which comes in handy if I do something stupid and delete some writing accidentally).
For example, in doing an edit on As You Were, I came to this one sentence:
She breathed cautiously at first,
–and felt it needed a little more zap, so I added:
…like some wayward astronaut stepping from the ship on some unfamiliar planet.
…and then i read the next sentence that was already there…and saw:
Then she tried to relax into it, as if some off-course astronaut taking first steps off the ship onto an unknown planet.
….call it “Diction DeJa-Vu”–Kinda scary when I do that. But at least I’m consistent.
