The Advanced Lady is a short story by Katherine Mansfield: "Do you think we might ask her to come with us," said Fräulein Elsa, retying her pink sash ribbon before my mirror. "You know, although she is so intellectual, I cannot help feeling convinced that she has some secret sorrow. And Lisa told me this morning, as she was turning out my room, that she remains hours and hours by herself, writing; in fact Lisa says she is writing a book! I suppose that is why she never cares to mingle with us, and has so little time for her husband and the child."
