What are a few common traits that characterize urban legends?

Urban legends often feature elements of caution or moral lessons, conveying societal fears or values. They typically involve a narrative that is easily relatable, often set in familiar environments, and can be presented as true stories. These legends often include exaggerated details and unexpected twists, making them compelling and memorable. Additionally, they tend to spread through Word-of-mouth or social media, evolving over time with each retelling.
