This document discusses how nonverbal communication conveys important messages through appearance, body language, silence, time and space. It explains that over half of communication is nonverbal and first impressions are formed based on nonverbal cues like dress, body language and tone of voice. Certain body language signals like open hands convey openness while crossed arms indicate defensiveness. Facial expressions, gestures, posture, eye contact and use of space all provide clues about a person's underlying feelings and attitudes.
