It’s difficult to remember in the heat of a disagreement that it takes two to quarrel. It may help to remember that no one can disagree with you while you are agreeing with them. This is not to suggest that you should compromise your principles. It is possible, however, to remain true to your beliefs while simultaneously searching for common ground that will enable you to work productively with others who may at first disagree with you. When others are upset with you or with a situation that involves you, let them know that you understand how they feel. Examine the problem from their point of view. What is the source of the conflict? How could it be resolved in a manner that would satisfy the interests of all involved? How have you contributed to the problem? When you try to find solutions instead of attempting to affix blame, others will almost always respond in kind.
It takes at least two people to carry on a quarrel.
