Essential communication
The way people communicate dictates their personal attribute towards one self and towards others. Effective communication skills would actually nurture good interpersonal relationship between individuals. For communication to effect, the non-verbal cues have to be in tandem with the words that pew out of an individual's mouth. The use of dialogues enhances motivation of an audience. Dialogues make the story more credible. This conversation breaks the monotony of narration. The writer posits that incorporation of dialogues in either in writings or speeches motivates the audience the most.
From my own life experiences, the non-verbal cues help one to determine the actual mood of an individual even without exchange of words. For instance, if an individual speaks to you with his face crinkled, it may be obvious to tell that the person may not be as happy as one may purportedly say. In addition, these cues may enable us to tell whether an individual is telling the truth or uttering words of deception.
