Social interaction refers to the exchanges and interactions between individuals aimed at establishing and maintaining relationships. It can take various forms, from casual conversations to formal business meetings, and interactions on online social networks. Social activities are crucial for individual psychological health and social well-being, as they help to build social connections and support networks, enhance mutual understanding, promote cooperation, and provide emotional support.

Socialization is also an important aspect of cultural and social structures, with different societies and cultural groups having their own unique social customs and expectations. For instance, some cultures might place a greater emphasis on family and close community ties, while others may value individualism and independence more.
