Respect

As a child we were taught to show respect for all adults. As a young adult we were taught how to earn respect from adults. As an adult we have been told that everything we had been taught as a child and young adult no longer applies. We are now expected to live by a whole new set of rules and respect should just come naturally. Is it just me or does it seem as if everyone just expects that they should be shown respect no matter what they do or say. Shouldn't you have to give respect to get respect from no matter what?
