Read the excerpt from the General Prolgue to The Canterbury Tales . There was also a nun, a prioress, Whose smile was unaffected and demure; Her greatest oath was just, "By St. Eloi!” And she was known as Madame Eglantine. She sang the divine service prettily, And through the nose, becomingly intoned; And she spoke French well and elegantly As she’d been taught it at Stratford-at-Bow, For French of Paris was to her unknown. Good table manners she had learnt as well: She never let a crumb from her mouth fall; She never soiled her fingers, dipping deep Into the sauce; when lifting to her lips Some morsel, she was careful not to spill So much as one small drop upon her breast. Her greatest pleasure was in etiquette. Based on this description of the nun, what conclusion can be drawn about the narrator?
