If someone does not know, is heading in the wrong direction, you may point out the right direction, then walk away.
Don’t be tedious with speech. Be considerate with what you say and do.
Never turn dialogue into argument or introduce anger or meanness, tolerate mistakes and walk away from a fight.
Stop quarrels with diplomacy.
