I think that the short story is like a different form from the novel and the poem, and the best stories perhaps seem to be closer in spirit to the poem than to the novel.
My first Wolff novel, although I would have preferred, as I have said many times, to start with his short stories. It seemed to me a good novel, with a good structure and a narrator who can be disconcerting at some points, halfway between autobiography, metafiction and fiction. Through the novel, we discover very well-structured literary criticisms, not only of his time, but also of the author himself, as a means to be able to move around, through fiction, and achieve a curious effect. An effect that I love, by the way.
I know Wolff through Carver, but also from what is usually called dirty realism. I don't quite understand this general-labeled term, but most writers of this style have Hemingway as a reference, a writer who has not only influenced literature in general, but also has a direct, austere style, without frills or hardly any symbolism. Although Wolff does use symbolism as a means of justification for the book. A school, students obsessed with succeeding in the world of literature, but who in the end, due to a plagiarism, failure is imminent, at least for our narrator, who turns out to be the plagiarist. A highly recommended literary juggling act. I have an incredible desire to read his short stories and his great novel, "This Boy's Life" which does have elements of autofiction and semi-biography. I recommend a documentary series that I know is available on "Filmin" about Hemingway, in which Wolff appears giving his opinion on various aspects of Hemingway's literature and life.
