Your story, for me, has come the closest to be a completely entertaining dialogue-only story. I've tried to write one myself, and it's an incredibly hard format.

I do like the scene you've written here, and even though your situation initially confused me, your set-up made and more personal view of the murder scene is the most entertaining and well-crafted part of the text. And the way the character's personalities play off of each other is fun to read.

The little asides are nice breaks in the discussion, but they don't feel quite natural. The asides about net slang IRL and anachonisms feel especially off, and with a story based entirely on dialogue, any stiffness in speech is going to be noticed.

I could go into nitpicks about grammar mistakes or issues, but I won't. I will ask you to read over the piece again and make sure you aren't glazing over errors by accident. I will say that your attempt at inserting italics can be jarring in places. To italicize a word on FictionPress (if you don't already know), load your document, click on the edit option, and use the italics button over the words you want italicized.

The whole discussion between the two writers made me want to know more about the first writer's project and a little bit about the second writer in general. Maybe that could play into an aside from the discussion or something.

I like the ending for its elegant simplicity. Nice job overall.
I'm not sure why you chose to seperate your author's note from the rest of the piece. You could have seperated the note with something as simple as a single line dash like this:

A/N: Blah blah blah

-

"So, what if I..."

Thanks for reading/reviewing Dearest Sister! Your comments about description were very true, and I will keep them in mind for the next chapters.
I really like the ideas you have going in this conversation. I loved that the diagoulge had so many levels: the two characters, their literature, your writing experiences mixed with theirs, real life, stroy life; it was all very interesting. I would advise going a little lighter on the profanity, but that's just my personal opion and disregard for bad language. Though at times it was a little confusing, I appreciated the lack of background information on the characters and their relationship as writers and as friends/lovers/rivals. I got to puzzel it all out however I wished to interprate it.
Thanks again,

This is interesting and amusing.
