Languages inside languages

Nowadays it is really easy to hear "developing critical professionals". What this simple phrase means is that the world is trying to bring people with opinions. They are motivating the discussions.

But what should be the meaning of that? They are surely not trying to develop personal fights, but rather to increase the exchange of information and reasoning. Some times it does happens, but when people from different cultures (what does not mean they are from different countries) come to talk, they rarely exchange information or do some reasoning. And the reason for that is that there are a bunch of different communication ways out there, that we could not see, but we sure feel.

For example, when talking to a criminal, you may found that the most important thing in the speech is to find a hierarchical position and maintain that. Anything that could broke that hierarchy in speech after it is have been established will undoubtedly bring only a fight. But if you keep that hierarchy in the talk, it could be very reasonable.
In a executive talk, it is almost the same. And in both kinds there are words that should and should not be used.
Can you imagine a executive talking like "fuck, do ya know what u've done boy?" or a criminal using difficult to understand words or too much politeness. But at a logical point of view their talks (criminal and executive), although opposites in some aspects have lot of equal characteristics, they are keeping the status in the speech.
An executive and a criminal will probably face problems while talking to each other, because they do not talk the same language.

A talk that would be very different is from a philosopher or from nerds. They also have some kind of fight inside their talk, but the essence of the talk is normally logical. The main point in the talk is the logical thought and everything is derived from it, even the status.

Aside from the cultural differences, there are also behavior characteristics. Some people like to talk loud, some get irritated with it. Some like to use flexible slangs others think it is too much inexact, some like to preserve a language pattern to show some status while others dislike status in speech, some like offensive charges in speech just like an army of arguments while others prefer to keep it calm, some get hurt personally others always consider talk a non personal thing.

With all these differences it is hard to imagine that people would have the same way of communicating, but the problem is, in what extent can they communicate and how this exchange takes place? Is it enough to discuss the subject?

Sometimes the answer is no. And in this world of languages inside languages there is just one way to talk, learn another language. And do not get me wrong, learning another language is not only memorizing words, it is more like understanding cultures and behaviors.
