I haven't read many vampire stories besides Anne Rice's Interview With A Vampire, precisely because I know they would be the sort of tripe that you cite up there in the Big Paragraph Of Doom. ;) If you were to write yours, though? I would be there encouraging and demanding you to hurry up every step of the way, and fangirl the finished product. I mean, a vapire-hunting librarian -- how much cooler can you GET? :DD

That has happened to me with fic before, also! I always make sure I leave the document open or the paper lying in plain sight once I finish & before I go to bed, or I'll completely forget the next morning.
