21. Repentance/Confession
It's hard for the two of them to argue normally; because they are so proud, so unyieldingly firm, Roy can never admit to an error and Riza will become a statue, standing before him in martyrish silence. Each of them is convinced of their undistorted rightness and unwillingness to acquiesce to the other.
Roy is always especially shocked, perhaps because Riza rarely reveals her opinion; he is used to her solid, dependable, agreeable—or at least non-judgmental—silence, her accommodating presence.
He goes home early on days when they argue. He can't think.
It is not until he is in bed, one arm thrown over his face to muffle the words, that he can admit that he is wrong.
