Respect and Authority

Why do we “listen” to somebody ? Here I do not mean hearing when I say listen I mean obey or follow. I think it comes from either respect or authority. Authority maybe given by someone else e.g. Teacher in school, boss at work, parents at home. Lot of times, most people do what these people tell you to do, because of the authority inferred on them. Because you are “supposed to” do what they say.
