What's Up?

Have you witnessed two people passing on a sidewalk and one greets the other by saying "How's it going?" and the other responds "Hey, what's up?"  Did you notice that neither one of their questions were answered?  Phrases like "What's up?", "How are you doing?", or "How's it going?" have seemingly become rhetorical questions.  Is it because McDonaldization has taken over our society and we simply do not have the time to respond with a proper answer?  If this is the case why pose the greeting in the form of a question?  Why not simply say "Hi, have a good day.", and avoid any possible delays by having the person answer you?  Why must our greetings be shrouded by a question that we really don't care to hear the answer of?  If we simply do not care to know how one is doing, we should not ask.  Pretending to care is deceitful, asking someone "How are you doing?" and walking away is like a slap in the face.  We may have the intention of caring but if we ask in rhetoric, we actually show that we do not care.  My mom always said if you don't have anything nice to say, don't say anything at all.  Some of you might say that you actually do care, and I believe some of you do.  But be honest think back to a time where you asked someone how they were doing, and they went into a long answer that started to sound like a country song.  Did you really stand there listening and engaged in the conversation offering helpful hints to all their problems?  I bet you were thinking, I really didn't need to know about the rash you are developing on your groin or I wish they would shut up so I can get back to what I was doing.  If we ask how someone is doing, we must be prepared for the answer.  If prior to asking you know that you aren't interested in the answer, simply say "Hi".
