Read the passage carefully. Women who have served in the Palace, but who later get married and live at home, are called Madam and receive the most respectful treatment. To be sure, people often consider that these women, who have displayed their faces to all and sundry during their years at Court, are lacking in feminine grace. How proud they must be, nevertheless, when they are styled Assistant Attendants, or summoned to the Palace for occasional duty, or ordered to serve as Imperial envoys during the Kamo Festival! Even those who stay at home lose nothing by having served at Court. In fact they make very good wives. For example, if they are married to a provincial governor and their daughter is chosen to take part in the Gosechi dances, they do not have to disgrace themselves by acting like provincials and asking other people about procedure. They themselves are well versed in the formalities, which is just as it should be.
