Seen it around, might as well do it myself
Pick any passage of 500 words or less from any fanfic I’ve written and comment to this post with that selection. 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, what’s going on in the character’s heads, why I chose certain words, what this moment means in the context of the rest of the fic, lots of awful puns, and anything else that you’d expect to find on a DVD commentary track.
