Pick a paragraph (or any passage less than 500 words) from any fanfic I've written, and comment to this post with that selection. I will then give you 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.
(I'm a bit edgy about this. At some point I was supposed to do a full-blown commentary for ficcommentary and I just couldn't get my sieve-brain around it. So I'm going to try this one on the small scale, if anyone is actually interested.)
