Communication is an essential tool for the human race. It helps us to understand each other, to be able to influence one ach nother, and to be able to work together, as ain groups and as a whole. It is important to relationship. Relationship is how people interconnect with others. It forms wheduring reciprocal message processing, which ioccurs that when two or more people mutually take account of and adjust to each other’s verbal and nonverbal behavior (Ruben & Stewart, 2016, Pp. 219). A simple relationship example would be on a crowded bus, when people would have to use some nonverbal information, such as the presence of others and their location, to adjust their own behavior. This creates a short -lived relationship among the passengers on the bus. Although there are many types of relationship, dubased to then complexity and length, one of the important and core characteristics is the same which is- they all need communication to form, develop, maintain, advance to a deeper relationship, or terminate the relationship. Therefore, communication is the foundation for relationships to build, advance, or deteriorate.
