One day my charwoman, a working man's wife, came to beg me to honor her sister's wedding with my presence. If you are to realize what this wedding was like, you must know that I paid my charwoman, poor creature, four francs a month; for which sum she came every morning to
make my bed, clean my shoes, brush my clothes, sweep the room, and make ready my breakfast, before going to her day's work of turning the
handle of a machine, at which hard drudgery she earned fivepence. Her husband, a cabinetmaker, made four
francs a day at his trade; but as they
had three children, it was all that they could do to gain an honest living. Yet I have never met with more sterling honesty than in this man and his
wife.
(from "Facino Cane" by Honoré de Balzac)
