The auditorium is often the place where the students will gather for any sort of assembly, activity or anything that the teachers have organized to happen unless told otherwise. It's where you will find your posted classes to be and often people just come around here to get away from the crowd since it is normally empty unless there's something going on. Though students aren't supposed to be here unless setting up something or have permission people will sneak in here either to fool around or just get away. The Auditorium isn't really used often but still of importance.
