Non-verbal communication

1. People often use their hands and gestures in order to get their point across. I often do that because it is easier for me to communicate what I am trying to say.
2. Face expressions are also a way of non-verbal communication. Based on what the persons expression is, you can tell if they like something or if they dislike it.
3. If someone is crying, it's obvious that they are sad and tears or smiles can also be a form of non-verbal communication.
