" Beware of those who attach great value to being credited with moral tact and subtlety in making moral distinctions. They never forgive us once they have made a mistake in front of us (or, worse, against us): inevitably they become our instinctive slanderers and detractors, even if they should still remain our “friends.”
Blessed are the forgetful: for they get over their stupidities, too. "

― Friedrich Nietzsche , Beyond Good and Evil
