(Disclaimer: any opinions are strictly my own, to do with as you will. Keep what you find helpful, toss the rest with yesterday's paper)
Dialogue is my weakest point as a writer. As such, I am humbled by your skill in this dialogue-only piece.
The conversation flows naturally. The story develops at a good pace. You create two distinct and believable character voices. The premise is a good one, and you do very well with it, expecially over the course of such a short piece.
The title and intro are both solid.
Even the use of profanity, which I do not tend to be a fan of, works well in this piece.
I have noted no errors
Thankyou for sharing your talent, although you have created a definite level of jealousy in this particular fan . Write On!
