Answer:
impression management
Explanation:
Erving Goffman is a sociologist most famous for his theory of social interaction through a symbolic point of view. In this theory, he compares individuals to an overall theater play. Under this theory, it can be said that the professor in this situation is engaging in impression management, meaning that he is concerned about presenting himself in a certain way in order to leave a very distinct impression in the minds of those that see him. This is done in order to control the way that society itself sees that individual, which in this case is the professor.
