Quirks are unique traits or habits that make individuals stand out. They can be small, like a specific way of laughing or a preference for a certain type of food. These little idiosyncrasies often add charm and personality, making people more relatable and interesting. For example, someone might always wear mismatched socks or have a peculiar way of greeting friends. In literature and film, characters with quirks often become memorable. Think of Sherlock Holmes and his obsession with solving puzzles or Luna Lovegood from Harry Potter, who has her own whimsical way of seeing the world. These quirks help to define who they are and make their stories more engaging.
