Social interaction is the fundamental process by which people act and react in relation to others, involving communication, mutual influence, and the creation of shared meanings and social bonds. It occurs at all levels of social life, from brief encounters between strangers to long-term relationships within families and close-knit groups, and in formal settings like workplaces and organisations as well as informal settings like social gatherings. Social interaction can take various forms, including verbal communication, nonverbal cues such as gestures and facial expressions, and the exchange of symbols and meanings. It is through social interaction that individuals develop their sense of self, learn social norms, establish relationships, and collectively construct social reality. The study of social interaction is a core focus of microsociology, aiming to understand the patterns and dynamics of everyday social life.
