This document discusses social communication and its essential aspects. Social communication refers to the transmission of information between people using technology or other means. It involves small talk, building rapport, expanding social networks, and informal communication. Small talk is casual conversation to open communication between unfamiliar people. Building rapport involves developing close relationships through techniques like mirroring another's emotions, posture, tone, and finding common interests. Social networks and business associations can be expanded through gaining knowledge, taking classes, trying new experiences, and practicing social skills daily. Informal communication occurs through casual conversations and can spread information quickly but also introduces risks of rumors and distortions.
