While the narrator of "Dry September" is reserved in terms of commentary, the characters are not. Most of the dialogue is disturbing, and uncomfortable to read. Racial slurs that would be unacceptable today are presented as acceptable speech in the story. Still, there are many things implied, rather than directly stated. Here's something interesting to do while you are reading. Notice how often character don't finish their sentences, and seem to trail of in mid-thought. This seems to be a symptom of the communication breakdown we see at every level of this story. From the dangerous rumor that drives the action, to the muteness of Minnie Cooper, and the silencing of Will Mayes, the story is deeply concerned with issues of language and communication.
At the end of the story, Minnie's friends are unable to silence her laughter and screams; although this is a tragic moment of psychological breakdown, it is also a moment of hope because her laughter and screams represent an attempt to communicate.
Hawkshaw's incomplete sentences reflect his anxiety over his inability to communicate effectively with the other men of the town.
