From a newsgroup post dated February 10, 2009:

So I’m cleaning my office, trying to get it fit to allow prospective homebuyers in it, and this includes sorting through papers and filing or tossing most of them, so that’s what I’ve been doing this afternoon, and I’ve just now been going through a stash of story ideas — print-outs of Usenet and SFF Net posts, scribbled notes of one sort or another, sketchy maps, correspondence with editors about planned projects, etc.

And one of the scribbled notes is a story idea I had completely, totally forgotten, which has the potential to be an absolutely beautiful, heartbreaking story. How could I not have remembered that one?

Note, June 8, 2017: I haven’t forgotten it again, but I still haven’t written it, either.
