It was something new in her thinking of Hurstwood. Other things followed from time to time, little things of the same sort, which in their cumulative effect were eventually equal to a full revelation. Carrie was not dull by any means. Two persons cannot long dwell together without coming to an understanding of one another. The mental difficulties of an individual reveal themselves whether he voluntarily confesses them or not.
Trouble gets in the air and contributes gloom, which speaks for itself.
Hurstwood dressed as nicely as usual, but they were the same clothes he had in Canada. Carrie noticed that he did not install a large wardrobe, though his own was anything but large. She noticed, also, that he did not suggest many amusements, said nothing about the food, seemed concerned about his business. The change was too obvious to escape detection. In time she began to feel that a change had come about, and that she was not in his confidence.
