More than what you see:
Communication is how we interact with the world. It is how we tell those around us what we like and don’t like, it is how we express our thoughts, wants, desires, and dislikes. It is how we tell people we are tired, and how we communicate to others how much we enjoy being around them. Communication is different from language, and many of us communicate with both words, gestures, and facial expressions on a daily basis.
