List three examples of a non-verbal communication.
1. Facial expressions: One example of non-verbal communication is facial expressions, such as smiling, frowning, or raising eyebrows, which can convey different emotions without the use of words.

2. Body language: Another example is body language, including gestures, posture, and movements, which can also convey meaning and emotions without speaking. For instance, folding arms or standing with a relaxed posture can communicate different levels of openness or defensiveness.

3. Eye contact: A third example of non-verbal communication is eye contact. Maintaining eye contact can communicate interest, attention, or attraction, while avoiding eye contact can communicate disinterest, avoidance, or deception.
