" After it happened I was at a loss for words. Haven't you said this yourself? Haven't you said this to a close friend who early in your friendship, when distracted, would call you by the name of her black housekeeper? You assumed you two were the only black people in her life. Eventually she stopped doing this, though she never acknowledged her slippage. And you never called her on it (why not?) and yet, you don't forget. "
