" One explanation for the effectiveness of making a person “feel felt” lies in the mirror neurons I talked about earlier. When you mirror what another person feels, the person is wired to mirror you in return. Say “I understand what you’re feeling,” and the other person will feel grateful and spontaneously express that gratitude with a desire to understand you in return. It’s an irresistible biological urge, and one that pulls the person toward you. "
