Does your person ever complain, and you think they are wrong? Today (or the next time this comes up), no matter how off-base you might think they are, provide no corrective dialogue and no sigh of exasperation but simply say something understanding such as, “I bet that did make you frustrated” or “I’m sorry you have had a rough start to your day.”
Coach’s Corner: Surprisingly, even the most bottom-line people appreciate simple empathy more than you might think. That is especially true when the person is used to you arguing with them.
