Flirting is a type of behavior that involves playful and lighthearted interactions between two people. It is often seen as a way to show interest in someone without being too serious. The term 'FRIVOLITY' is used to describe this kind of behavior, which is characterized by its lack of seriousness and commitment. FLIRTATION is a more intense form of flirting, which involves more direct and intimate interactions between two people. It is usually done with the intention of developing a romantic relationship.
