My first stop during this observation tour was the most common place where man gathers in order to openly display their non-verbal communication skills and human relationships, the mall. I took my time walking around the building in order to observe men, women, and children and how they interact with one another. What I observed was that the most common human relationship that can be found and observed in the mall is that of varying degrees of friendships. Now DeVito defines friendship as, an interpersonal relationship between two persons that is mutually productive and characterized by mutual positive regard ( 187 ). Almost everyone that I observed arriving in pairs, as a group or meeting other persons at the mall prove the interpersonal relationship of their acquaintance because of the way they react to one another. It is not uncommon to observe these pairs or groups delivering non-verbal assurances of their friendships through their reactions to one another. From a warm hug, a kiss on the cheek, or even slapping one another on the shoulder all translate into non-verbal communications that prove that they consider each other unique, genuine, and irreplaceable individuals in each other life. But that is not to say that only positive friendships exist at the mall. Once in a while, I also noted the existence of discord between the couples or group individuals. These non-verbal arguments included the raising of an eyebrow as they discuss amongst themselves. The rise of an eyebrow is normally followed by a change in the vocal pitch of the person speaking.
