spatial distances

Every person has a particular space that they keep to themselves when communicating, like a personal bubble. When used as a type of nonverbal signal in communication, proxemics helps to determine the space between individuals while they interact. There are four types of proxemics with different distances depending on the situation and people involved. Intimate distance is used for close encounters like embracing, touching, or whispering. Personal distance is for interactions with close friends and family members. Social distance is for interactions among acquaintances.
There are four forms of human territory in  theory. They are:public territorya place where one may freely enter. This type of territory is rarely in the constant control of just one person. However, people might come to temporarily own areas of public territory.
interactional territory. place where people congregate informally home territory. place where people continuously have control over their individual territory body territory the space immediately surrounding us;
stand-your-ground law is a law that authorizes a person to protect and defend one's own life and limb against threat or perceived threat, and states that an individual has no duty to retreat from any place he/she has a lawful right to be and may use any level of force.
These different levels of territory, in addition to factors involving personal space, suggest ways for us to communicate and produce expectations of appropriate behavior.
