She seldom went farther than the ledge, these days, and she could not keep her mind off Johnny Jewel, even when there was no doubt at all that he was nearly as well as ever.

She might as well be a stick or a stone, she told herself viciously, for all the attention Johnny Jewel ever paid to her.

Mary V made the mistake of not putting herself in Johnny's place and from that angle interpreting his preoccupation.

Had she done that she would have seen at once that Johnny was fighting a battle within himself.
