Avoid Wanting To Win In Every Argument
Often, the trap of confusing discussions with contests in which you have to stay ahead of the other falls, whatever the cost. This only fuels the conflict, of course.
But, paradoxically, an argument is also an opportunity to reconcile, because your self shows that you are capable of not being carried away by the impulses that lead you to get angry, and shows understanding and empathy, this is a powerful show of love, and will contribute that the other person has reasons to build bridges, seeing that on the other side there is someone listening.
