Shortish (1,800 words, give or take?) and with the sense of this being just a few slices out of their life. If you like domesticity, particularly if you prefer your fic (even your slashfic) to be about questions other than will-they-or-won't-they, this may well be for you. It had me smiling fondly pretty much from start to finish.
