"It had begun to dawn on him that this same sweet pretty little head was a "good head for figures." In fact, a much better one than his own and the knowledge was disquieting. He was thunderstruck to discover that she could swiftly add a long column of figures in her head when he needed a pencil and paper for more than three figures. And fractions presented no difficulties to her at all. He felt there was something unbecoming about a woman understanding fractions and business matters and he believed that, should a woman be so unfortunate as to have such unladylike comprehension, she should pretend not to. Now he disliked talking business with her as much as he had enjoyed it before they were married. Then he had thought it all beyond her mental grasp and it had been pleasant to explain things to her. Now he saw that she understood entirely too well and he felt the usual masculine indignation at the duplicity of women. Added to it was the usual masculine disillusionment in discovering that a woman has a brain."
