how does being sociteal affect the way people interact with each other vs personal rules? what are the boundaries

There are different types of relationships that we Americans use. Societal affects how people interact by establishing whats appropriate for that situation. An example would be the relationship between the cashier and customer. The cashier is doing his or her job by checking the customer out. It is not appropriate for the Cashier to ask the customer why they made grocer's and it is not appropriate for the customer to ask the customer, what time does she or he get off from work. That would be rules of society. Personal rules affect family,lovers and friends. This relates to my boyfriend and I. We interact on the basis of personally establish rules. The way we touch each other ,look at one another and talk to each other. In our relationship,we have boundaries meaning, things I talk to my girlfriends about, I would not share with him.jstor.org/stable/256362?cookieSet=1
