Interestingly, human beings are natural “communicators”, whether by intent or by default. The difference is whether we always express what we really mean, in the way we deliberately choose, and in a climate of harmony.
Communication by intent is, the desired objective. The reality is somewhat different. Only rare individuals are natural, talented communicators. As for acquiring any skills, most of us have to practice consciously and get some form of training depending on our innate aptitudes. Some notions have to be explained and used, allowing individuals with poor dispositions to improve, and those with standard capacities to excel.
