When I make myself imagine what it is like to be one of those women who live at home, faithfully serving their husbands—women who have not a single exciting prospect in life yet who believe that they are perfectly happy—I am filled with scorn. Often they are of quite good birth, yet have had no opportunity to find out what the world is like. I wish they could live for a while in our society, even if it should mean taking service as Attendants, so that they might come to know the delights it has to offer.
