The danger of perceiving someone to be so full of a certain quality is that when he or she fails to act in accordance to that quality or worse still, acts in a way contrary to it, one shall readily lose that noble impression of the person. Suppose, for example, that you have always thought a person to be especially kind in her words, and who would never, even if in a lowly mood, employ the barb of cynicism. And then one day, she does. You are surprised, but more than that, you are disappointed. So confident you were of her dainty character; and now she tarnishes it. The perfection is lost. Indeed, how is glaring that little stain on the ivory surface.
