“Conversation, to take another example, is one of the common pleasures of life, but not all conversation is pleasurable. The stutterer finds talking painful, and the listener is equally pained. Persons who are inhibited in expressing feeling are not good conversationalists. Nothing is more boring than to listen to a person talk in a monotone without feeling. We enjoy a conversation when there is a communication of feeling. We have pleasure in expressing our feelings, and we respond pleasurably to another person's expression of feeling. The voice, like the body, is a medium through which feeling flows, and when this flow occurs in an easy and rhythmic manner, it is a pleasure both to the speaker and listener.”
