This document summarizes Erving Goffman's book "The Presentation of Self in Everyday Life" from 1959. It discusses how individuals seek to control the impressions they give off to others during social interactions. People convey information verbally through communication, but also non-verbally through expressions given off. Others observe both channels to form opinions and check for inconsistencies. Individuals try to strategically manage both controlled and seemingly uncontrolled expressions to shape the definitions of situations and responses of others. This sets up an ongoing game of revealing, concealing, and discovering true impressions between actors and their audiences.
