Erving Goffman analyzed social interaction and developed the idea of impression management. He viewed social interaction as a performance where people aim to control how others perceive them. People pay attention to non-verbal cues and use props to strengthen their performance and desired impression. Interactions have a front stage where people maintain their impressions and a backstage where impressions can slip. Roles are defined through interaction but people sometimes distance themselves from roles to show they are complex. While roles are influenced by social institutions, people have agency in how they define and enact their roles.
