In fact, much of what we communicate comes through the nonverbal cues we send. Take, for instance, when you're walking down a sidewalk and see someone coming towards you. If your eyes meet, one of two things happens. You continue to hold eye contact and acknowledge one another's existence, or you look away. In both cases you're communicating without saying a word.
Personal space is important in nonverbal communication.
We're basically territorial. Personal space also moves with us. It is within this space that we use nonverbal communication. Three different forms of nonverbal communication are body movement, facial expression, and eye contact. Body movement includes running, walking, signaling, and body position.
