1. Shake hands
This type of body language is commonly used in formal or polite situations. For example, when two people meet for the first time in a business meeting, they often shake hands as a sign of respect and introduction. This gesture shows friendliness, openness, and the intention to create a good relationship.

2. Stare at someone
This body language often happens in uncomfortable or tense situations. For instance, a teacher might stare at a student who is misbehaving in class. The long, intense eye contact sends a clear message of disapproval or seriousness, making the other person feel observed or judged.

3. Wave to go away
This body gesture is usually seen when someone wants another person to leave or stop bothering them. For example, a mother might wave her hand at her child to tell them to go away while she is on the phone. This movement expresses urgency, annoyance, or a need for space without using words.

4. Nod
This type of body language is often used to show agreement or understanding in a conversation. For example, while listening to a friend talk about a difficult situation, someone might nod to show they are paying attention and understand. It is a quiet way to express support and empathy.

5. Cross arms
This gesture is usually seen when someone feels defensive or uncomfortable. For instance, a teenager might cross their arms while being scolded by a parent. This action can show resistance, annoyance, or a desire to protect oneself emotionally from the situation.
