How to become an effective communicator.
Confirm that you have a mutual understanding of what's being communicated.
We often think that we've reached a resolution and come to an understanding, only to find out that we have completely misunderstood the other person's thoughts.
This not only confirms that you have successfully communicated; it also makes the other person feel that they have been heard and understood.
mutual adj.共有的； 共同的； 相互的； 彼此的
