Erving Goffman's concept of Dramaturgy provides a logical analogy to the nature of human interaction that society consists of. People participate in social interactions from the time they first understand that other people exist. During each encounter, a certain understanding of the significance or meaning of the interaction is observed and exchanged which provide the basis for the meaning of future interactions. Individuals assume various roles in the interactions that they are acting in the same way a theatrical stage actor might approach a role depicted in a play. The clothing or attire individuals wear serve the same purpose a thespian wears a costume, to project a believable persona or self to the audience. Individuals will choose a setting that is conducive to the goal of an interaction which provides the setting that will cause a successful outcome to a given performance. Mannerisms provide individuals with visual cues that help actors portray their "selves" to the persons they are trying to communicate with. Individual actors may be sincere or deceiving in the the performance given during social interactions.
Are you consciously aware of yourself performing like an actor in everyday societal interactions?
