Communication can be the most important aspect of any relationship. Communication is the key to letting others know how we feel and what we need. We communicate in many ways. Our body language and our walk can communicate who we are, how we are feeling, and the condition of our health. Our eyes communicate feelings and opinions. Even sighs and groans communicate. The way we touch, or do nottouch, tells others about us. Our words are not the only communication tools we use.
