Friedrich Nietzsche

Human, All Too Human

In Relations With Others

346 Unintentionally impolite. -When someone unintentionally treats another person impolitely, not greeting him, for instance, because he does not recognize him, this rankles inside him even though he cannot reproach himself for his own intentions; the bad opinion that he has engendered in the other 3o person vexes him, or he fears the consequences of ill feeling, or it causes him pain to have injured the other person-hence vanity, fear, or pity can be stirred, perhaps all of them together.
