Setting and scene also refer to implicit rules and expectations surrounding the speech event. For instance, the setting of the speech event determines who should speak and who should not, what type of speech is appropriate (code-switching), and when interrupting is acceptable. For instance, speech events in the classroom have specific implicit rules for teachers speaking and students listening, certain words are not viewed as appropriate in the classroom, and interrupting is often met with consequences. Conversely, different implicit rules and expectations apply at social gatherings and work settings.
