Monologue is a single speaker talking. It is talking without listening. Monologue is the culmination and conclusion of suspicious talk. It is the talk of those so suspicious of others that they trust no one but themselves.
There is no community in monologue. It is the talk of those who have closed themselves off from others and are tormented by their isolation and loneliness.
Monologue is old King Saul brooding about his sins and suspicious that a shepherd boy was plotting to seize his throne. (1 Samuel 18:1-15)
