Interpersonal communication is complicated

No form of communication is simple.  Because of the number of variables involved, even simple requests are extremely complex.

Theorists note that whenever we communicate there are really at least six “people” involved:

We don’t actually swap ideas, we swap symbols that stand for ideas. This also complicates communication.

Words (symbols) do not have inherent meaning; we simply use them in certain ways, and no two people use the same word exactly alike.
