Not that I (exactly) regret agreeing to sign up for the fic exchange, but it would be a lot easier if I could just call it "original fiction" and have done with it.
Anyway, I shall be attempting to pin the thing down in words in the comments, because that's succeeded before as a last-ditch pyschological work-around. And this post is public because if it's locked that entirely ruins the effect on me. But I think the fic-exchange is supposed to be anonymous (I'm not sure?), so if you do read along as I'm posting it, pretend you didn't until after the 20th.
