Erving Goffman

In many kinds of social interaction, unofficial communication provides a way in which one team can extend a definite but non-compromising invitation to the other, requesting that and formality be increased or decreased, or that both teams shift the interaction to one involving the performance of a new set of roles.

Often, when two teams enter social interaction, we can identify one as having the lower general prestige and the other team the higher. Ordinarily, when we think of realigning actions in such cases, we think of efforts on the part of the lower team to alter the basis of interaction in a direction more favourable to them or to decrease the social distance and formality between themselves and the higher team. Interestingly enough, there are occasions when it serves the wider goals of the higher team to lower barriers and admit the lower team to greater intimacy and equality with it.

The self... is not an organic thing that has a specific location, whose fundamental fate is to be born, to mature, to die; it is a dramatic effect arising diffusely from a scene that is presented.
