It depends. Some writers indent paragraphs for better readability, while others don't. It's a matter of personal style.
Whether to indent paragraphs in a short story is up to you. Some find indenting helps organize the text, but others might think it's not essential. It's really about what makes the story look and flow best for you and your readers.
Not necessarily. Indenting paragraphs in a short story is more of a formatting choice. You can do it to create a visual break, but it's not a strict rule. Some authors prefer to use spacing instead.
