Who wrote the chapter "To Wives?” Was it Lois?

Bill W. was the author of the "To Wives" chapter. It is commonly thought that his wife Lois wrote it. But, as 'Pass It On' describes (page 200), Lois said, “Bill wrote it, and I was mad.” She added, “I wasn’t so much mad as hurt. I still don’t know why Bill wrote it. I’ve never really gotten into it — why he insisted upon writing it. I said to him, ‘Well, do you want me to write it?’ And he said no, he thought it should be in the same style as the rest of the book.”
