Answer:
"The petrified man" by Eudora Welty uses grotesque imagery to establish the most significant themes through the characters of the story, there are two main characters and the whole story goes around the conversation between them, who in a very dark, twisted and unpleasant way criticize and diminish the life of others, pretending to be worrying about them and their whereabouts, all the people that are being cynically analyzed in this piece of work are the clients of Leota, a beautician, her and her customer, Mrs. Fletcher are representations of the most despicable "qualities" of the human beings, the sense of grotesque in the story is created in the atmosphere by the way these two characters interact and how they personalities seem to be built only over darker shades of selfishness, irony, and sarcasm. These characters feel that they are morally superior somehow, which gives them the right to scrutinize the clients' lives
