I thought the idea of the story was interesting, but I felt like the dialogue was forced. It seemed like Walter and Stacey were making speeches, not having an actual conversation. In a real conversation between two people in this situation, I'd expect them to get animated, interrupt each other on occasion, and sometimes be unable to find the right words for what they want to say, especially in such a frank conversation.

One other thing I noticed was that it's never said where this conversation takes place, what they're wearing, or how either of them really feels. You try to use "he inquired" or "she wondered" to express emotion, but it seems limited and I think that contributes to why I felt like they were making speeches to each other.

My inner grammar queen is pretty happy, I must say. I didn't see any real issues with that, which always makes me happy.

I know that it can feel like there's always more things to think about at once and that it can be a bit intimidating, but I think you can make this into a fine story Severusmax. I really do.
