If I quickly apologise when I make a mistake riding my bike or driving the car, I can often see their anger melt away.
If I respond gently to the children's anger, the situation normally diffuses quickly. If I show my annoyance, it escalates.
If I have upset someone unwittingly and humbly apologise to them, then both of us will have a better day.
We all need to be humble enough to answer people gently and not use the conflict to ease our wounded pride or assert our rights.
Easy to type, hard to live out, excellent to pursue.
