Children or adolescents with Selective Mutism may avoid eye contact, freeze, blush, or stare blankly when addressed by people whom they are unfamiliar with. Some might refuse to follow the adult's directions, which might seem like they are being disobedient or defiant. They may withdraw, avoid or 'shut down' in social situations which makes them feel anxious or stressed. Hence, they may not respond to greetings outside of the home environment.
