1. Shaking Hands
Shaking hands is a common gesture in formal or respectful settings. It often happens when two people meet for the first time, especially in professional environments like business meetings. This simple act shows friendliness, openness, and a willingness to build a positive connection.

2. Staring at Someone
A prolonged stare usually occurs in tense or uncomfortable situations. For example, a teacher might fix their gaze on a student who’s acting out in class. This intense eye contact communicates disapproval or seriousness, often making the other person feel judged or pressured.

3. Waving Someone Away
Waving someone away is a nonverbal way of asking someone to leave or stop bothering you. Take the example of a mother who waves her hand to her child while on an important phone call — it’s a quick way to show urgency, frustration, or a need for space without saying a word.

4. Nodding
Nodding is a subtle but powerful gesture used to show agreement, understanding, or support. During a conversation, especially when someone is sharing something emotional or personal, nodding indicates that you’re actively listening and empathetic.

5. Crossing Arms
Crossed arms often signal discomfort, defensiveness, or emotional distance. A teenager being scolded by a parent might instinctively cross their arms as a way of showing resistance or protecting themselves from the emotional impact of the situation.
