For this reason marital dyads are often enforced through legal, economic, and religious laws.
Already Ferdinand Tönnies treated it as a special pattern of gemeinschaft, 1887, as community of spirit.
In practice, this relationship refers to dialogic relations or face-to-face verbal communication between two people involving their mutual ideas, thought, behavior, ideals, liking, disliking, and the queries and answers concerning life and living in nature.
Examples of dyadic communication occur between Jesus and Peter, the Buddha and Ananda, or between Socrates and Plato, where dialog is not only outward, superficial, or mechanical, but instead brings the two people into a sphere where each person influences the other.
