Think for a moment of all the bodily and mental activity that accompanies even the simple act of saying “hello” to a friend. From the stimulation of your nerve endings, to the secretion of chemicals in our brain, to the moving of your lips to produce sound, thousands of components are in operation (and most of them at the same time). Notice how the notion of complex it is clearly captured in the following observation advanced by Smith: “Human communication is a subtle and ingenious set of processes. It is always thick with a thousand ingredients-signals, codes, meanings, no matter how simple the message or transaction.” Communication becomes even more complex when cultural dimensions are added. Although all cultures use symbols to share their realities, the specific realities and the symbols employed are often quite different. In one culture you smile in a casual manner as a form of greeting, whereas in another you bow formally in silence, and in yet another you acknowledge your friend with a full embrace. Another reason why communication is complex is that people are alike and they are different.
