When confronted with the dilemma of being right, or being kind, choose kindness. Believe me, there will be other opportunities to make your point (if it is important enough) without confrontation or dispute.
Pray for opportunities to resolve disputes, there’s no reason to deal with anything alone. God is able to do that which we are not quite able to manage on our own.
A soft answer turns away wrath, but a harsh word stirs up anger.
The beginning of strife is like letting out water, so quit before the quarrel breaks out.
