Think about this for a second... you are walking, minding your own business and someone greets you with "hey, how are you?" do they really care? or are they just saying that to make it seem like they care?
As I walk through the mall, see a familiar face, the first thing they ask me is "hey, how are you?" with a huge smile. Of course, me being a smartass, wants to tell them how I am. I could say, "I am doing well you know. I just finished school. I am looking for a job now and not really doing too much." but do you think they care? I don't. So I respond with, "Fine. and yourself?" like I really care. The American culture has this rapid lifestyle. From things like drive thrus to fast food, americans (me included) are always running from one thing to another. When I was in Spain, the Spainards took their sweet time to wherever they were going. Why can't the americans be like this? relaxing, calm, all the above.
so remember next time you ask someone "how are you?" do you really care how they are doing or are you just finding words to fill the space so you don't look like a deer lost in the headlights? just a little food for thought in my own words!
