Politeness a lost practice?

     Many of us, that is, the circle of friends that I am with, knows the importance of politeness and manners that have been imbedded in us since we were at a tender age. What is it then that causes some of us to not have this practice even if we are all of the same race. I mean like, in my culture, I have been taught that respecting the elders is very important in our family and our race, and thus we take into account "calling" and "respecting" elders whenever we meet them. "Aunty" or "uncle" is very much the common "names" that we use to call, and being from the same race, I can't see why some of us do not practice them? After all, cultural behaviour has been taught again and again such that it should be the same. And the most mind boggling experience? The fact that this culture is lost to those who are educated and have been blanched by cultural experiences and parents which are very much embedded in the essence of our culture.
     While people who are of the same race but may have been brought up with a different first language, and have been labelled as "westernized", in fact they actually take into practice this culture and respect when calling an elder, to greet with cheerfulness and most importantly being loud, clear and heard. I have encountered such cases many times before and I do not mean to be offensive of whatsoever. In fact, what I'm trying to point out that if this culture is lost among us now, what then can be said of our fellow children of the future?
I do not know what the cause may be for such a behaviour from some, but I have heard of too many cases to not point this out. Maybe it is your character, or a simple explanation that you have not been well taught by your parents, whatever it may be, I just hope that young people out there learn the importance of respecting elders and calling them when you first meet.
     Remember, the first impression tells a lot about a person. Put yourself in their shoes, take yourself a few decades older and think, if there was a young girl or boy standing in front of you, would you like it if they just stared at you or even worse, ignore you and continue doing whatever they may be doing?
    Always acknowledge, and be clear when you greet. This is respect. If you do not know how to do it, how then, can you teach your young ones in the future? And if this culture is lost, many other young ones may do it to you too.
    Don't let our culture be lost, even in our OWN race.
