social and unsocial The difference between social and unsocial lies in behavior, interaction, and engagement with others: Social Actively interacts with others. Enjoys company and group activities. Communicates and engages in conversations. Builds and maintains relationships. Friendly, outgoing, and cooperative. Unsocial Prefers to be alone or avoids social interactions. Not interested in group activities. May be reserved or introverted but not necessarily rude. Avoids socializing out of personal choice, not hostility. Focuses on personal space and solitude. Note: Being unsocial is different from being antisocial . "Antisocial" means acting against social norms, sometimes in a harmful way, whereas "unsocial" just means avoiding social interactions.
