Curtain Fic

Fanfic that has a domestic chore as the plot. The classic situation is shopping for curtains, hence the name. Other sorts of shopping also work.

This can also mean just a fic of a couple, either Het or Slash, spending the day at home.

This is a variety of WAFF, a fan-created Breather Episode; the point is showing the characters doing something quiet and mundane together. Interestingly, this genre is popular even (especially?) for fandoms where the work itself (including official Breather Episodes) is action-packed. The phenomenon of Fanfic written about characters shopping for curtains was first noted in an on-line article about fanfic for The Sentinel.

True Curtain Fic rarely contains sex; the trip to IKEA rarely ends with IKEA Erotica. This is all about character study, or else about getting the plot more paper-thin as someone who doesn't want to write Lemon fic will get.

This can also be played for laughs when a character with No Social Skills acts like a Fish Out of Water for something as "simple" as buying toilet paper; see also Villains Out Shopping.

Anime and Manga

 * Tampon has Edward Elric going on the Errand Of Doom: picking up tampons for Winry. And it is adorable
 * The Second Try is an interesting take on this, since the activities in question are survival in a post-Third Impact world and revolve around things like getting food, self-education and property maintenance. It's also notable in that it provides significant Character Development for Shinji and Asuka as well as numerous Heartwarming Moments.
