Carl Rogers said this quote

Hearing has consequences. When I truly hear a person and the meanings that are important to him at that moment, hearing not simply his words, but him, and when I let him know that I have heard his own private personal meanings, many things happen. There is first of all a grateful look. He feels released. He wants to tell me more about his world. He surges forth in a new sense of freedom. He becomes more open to the process of change. I have often noticed that the more deeply I hear the meanings of the person, the more there is that happens. Almost always, when a person realize he has been deeply heard, his eyes moisten. I think in some real sense he is weeping for joy. It is as though he were saying, Thank God, somebody heard me. Someone knows what it's like to be me.
