But little Johann saw more than he was meant to see, and his eyes, those shy, golden brown eyes ringed with bluish shadows, observed things only too well. Not only did he see his father’s poise and charm and their effect on everyone, but his strange, stinging, perceptive glance also saw how terribly difficult it was for his father to bring it off, how after each visit he grew more silent and pale, leaning back in one corner of the carriage, closing his eyes, now rimmed with red; as they crossed the threshold of the next house, Hanno watched in horror as a mask slipped down over that same face and a spring suddenly returned to the stride of that same weary body. First the entrance, then small-talk, fine manners, and persuasive charm—but what little Johann saw was not a naïve, natural, almost unconscious expression of shared practical concerns that could be used to one’s advantage; instead of being an honest and simple interest in the affairs of others, all this appeared to be an end in itself—a self-conscious, artificial effort that substituted a dreadfully difficult and grueling virtuosity for poise and character. Hanno knew that they all expected him to appear in public someday, too, and to perform, to prepare each word and gesture, with everyone staring at him—and at the thought, he closed his eyes with a shudder of fear and aversion.
