Nonverbal communication refers to the use of body language, facial expressions, and gestures to convey messages without using words. "Listen with the eyes" is a true statement because nonverbal cues such as eye contact, facial expressions, and body movements can provide important information about a person's emotions, intentions, and attitudes. By observing these nonverbal signals, one can effectively "listen" and understand what the other person is trying to communicate, even without them speaking.
