Listening is circular, and ends with the originating speaker receiving a message they need to respond to. There is a speaker and a listener, a message maker and a message receiver. And without a Sender and a Receiver, there is no message. Indeed, the definition of a communication includes having a sender and a receiver. In my humble opinion, listening is the most important part of a communication, because if we don’t hear what is being said, there are no grounds for communication.
How do you know you are hearing what is intended for you to hear?
