Apathy

The dictionary definition for apathy is: lack of interest in or concern for things that others find moving or exciting.
     What is apathy caused by? Self-centeredness? Difference of opinions? Do human beings simply have an ability to turn off the "caring" part in them? Is it always voluntary? And if not, is there a way to turn the "caring" part in them back on? Could apathy potentially be a sign of a much bigger issue?
     And who can distinguish apathy from, potentially, anger, frustration, or stress? Or do they go hand in hand?
A lot of times, when a person displays apathy, whomever they display it to may become upset. Who is this unfair to? The apathetic or the receiving end of apathy? It changes in each situation, right? So what are we to do? Use our best judgement, act wisely, and prevent upset. Apathy can fall under many different categories, such as: ignorance and rudeness, so it should be treated the same way. Properly.
