Pick any passage of up to 500 words or less from any fanfic I’ve written, and stick that selection in a comment. I will then give you the equivalent of a DVD commentary on that snippet: what I was thinking when I wrote it, why I wrote it in the first place.
The lion's share of myfanfic is available
here.
ETA: The 500-word limit is from the original meme. Seems like a decent length, but I'll be a bit flexible.
