What usually has a limited number of characters and focuses on a single event or insight?

A short story typically has a limited number of characters and is designed to focus on a single event or insight. This format allows for a concise exploration of a theme or idea, often culminating in a moment of revelation or emotional impact. The brevity of a short story means that every character and detail must serve the overall purpose of the narrative, leading to a tightly woven plot.

In contrast, novels contain more complex plots and multiple characters, exploring broader themes over a longer duration. Poems, while they can express deep insights and emotions, often focus on language and form rather than a linear narrative about a specific event. Drama, on the other hand, involves dialogue and action intended for performance, typically encompassing multiple scenes and possibly numerous characters, which may stray from the singular focus typical of short stories. Thus, the characteristics of short stories make them uniquely positioned to fulfill the requirement of highlighting a limited number of characters and centering on a single event or insight.
