We're all brought up a certain way by our folks, and to say that we were brought up wrongly, would be, well – just, wrong. It is the environment that that influences this bringing up on our peers, and our sociable circle and thus, us.
The two types of environment that I talk about are the direct influence group (that directly influences our behavioral change through a certain time period) and the indirect influences (which influence through a certain means or group of individuals).
But where does the act of conversation fall into? Both, I would assume, because of strong influence both groups have on a certain talk module such as word of mouth, direct individual and group relationships and external changes imposed in an direct and an indirect way on both these groups.
However, talk conversations politeness have started going from the easy-going 'Oh my Lord!' to 'Oh, [censored]!' It has become widely common to use street swear slang in normal conversations as it is to wear a sleeveless and shorts in public by both genders.
What's more worse is that we have become more tolerant to the entrance to other street swear terminologies that we have come to not object on them by the excuse of 'being cool'; or 'taking in the trend'; or even 'grasping modern day art'.
Let's face it – the art of conversation is dying taking our very own traditional linguistic high values along with it.
