Communication is an open, self-organizing system where many elements interact.
Is this statement correct or not correct?
Communication is not only sending a message to another person. What we think has an impact on what we feel and what we feel has an impact on what we do and what we say. Emotions and memories play an important role in our communication.
"One cannot not communicate" is the famous notion of Paul Watzlawick, an Austrian-American family therapist, psychologist, communication theorist, and philosopher (1921-2007).
Every behavior is a form of communication. Because behavior does not have a counterpart (there is no anti-behavior), it is impossible not to communicate. Even if communication is being avoided, that is a form of communication.
Non-verbal communication tells a lot about our feelings and about the kind of relationship we have with strangers - and with guests. Positive Communication is also expressed in positive non-verbal communication, including body language, gestures or facial expressions.
Also in non-verbal communication there can be misunderstandings due to different perceptions of body language and gestures. We all have to learn how to interpret non-verbal communication.
But some fundamental expressions of our face, such as anger, joy, fear, sadness, surprise or disgust, are universal. This means, usually every human being understands.
