Why is a fable so short?

A fable is typically short because it aims to convey a moral lesson or insight in a concise and easily digestible format. This brevity allows the story to focus on essential characters and events, making it accessible and memorable for readers of all ages. The simplicity of the narrative helps to emphasize the moral without unnecessary complexity or distraction. Ultimately, the short length enhances the fable's effectiveness in teaching important life lessons.
