Sheila is a black executive at a company that is almost entirely all-white. she jokes with her mother that when she goes to work she "checks her blackness at the door." erving goffman might say that at work she is her self.

Erving Goffman might say that at work she is her presentation of self. Erving Goffman is a sociologist known for studying microsociology. According to his theory, people present themselves in different ways according to the people around them, just as an actor does before going out to act in a play. Human behavior would be the result of all the "actions" that people perform in the different contexts in which they interact.
