Proxemics is the study of how people use physical space when they interact with others. People use the space around them to communicate their feelings and emotions, and you can learn a lot about the relationship between two people by looking at the way they use space. For example, people who are close friends or family often stand or sit close to each other and make physical contact like hugging or holding hands. On the other hand, people who don't know each other may stand further away and not touch.
