Primary_And_Intimate_Group represents the most fundamental and emotionally significant social aggregates characterised by face-to-face interaction, emotional intimacy, and strong personal bonds among members. These groups typically involve small numbers of individuals who know each other personally and interact regularly in informal, spontaneous, and deeply meaningful ways. They serve crucial functions in socialisation, emotional support, identity formation, and the transmission of values and norms. The relationships within these groups are often diffuse and multifaceted rather than focused on specific tasks or objectives. These aggregates provide the foundational social experiences that shape individual personality, self-concept, and basic social skills, representing the most immediate and influential social environment for most individuals throughout their lives.
