I am increasingly jealous of another very strong dialogue-only piece.
I have done door-to-door sales before (the industry calls this canvassing. It's hell) and can thus appreciate thsi work more so than most. The pitch is realistic.
Each voice in this work is distinct and believable. You create a character in your salesman that people can have sympathy for.
The story you create is amusing. The plot is quick, and developed in a clear manner. It's a cute little gem all around.
I love the introduction of the husband's voice at the end of this piece, and the second 'voice' his wife takes on, that is just as true and realistic as the rest of the dialogue.
I have noted no errors.
Thankyou for sharing this great bit. I will try to take notes and learn something Write On!
