It was dusk; she had come in to see Nannie and talk over that illuminating suggestion: _why not live on the principal?_ But Nannie was not at home, so Elizabeth sat down in the firelight in the parlor to wait for her. She sat there, smiling to herself, eager to tell Nannie that she had argued Cherry-pie into admitting that the plan of "living on the principal" was at least feasible; and also that she had sounded her uncle, and believed that if she and David and Cherry-pie attacked him, all together, they could make him consent!--"But of course David will simply have to insist," she thought, a little apprehensively, "for Uncle Robert is so awfully sensible." Then she began to plan just how she must tell David of this brilliant idea, and make him understand that they need not wait; "as soon as he really understands it, he won't listen to any 'prudence' from Uncle!" she said, her eyes crinkling into a laugh. But how should she make him understand? She must admit at once (because he was so silly and practical) that, of course, the interest on her money would not support them. Then she must show him her figures--David was always crazy about figures! Well, she had them; she had brought them with her to show Nannie; they proved conclusively that she and David could live on her capital for at least two years. It would certainly last as long as that, perhaps even for two years and a half! When they had exhausted it, why, then, David's income from his profession would be large enough; large enough even if--she blushed nobly, sitting there alone looking into the fire; "even if!" Thinking this all out, absorbed and joyous, a little jealous because this practical idea had come to Nannie and not to her, she did not hear Blair enter. He stood beside her a moment in silence before she was aware of his presence. Then she looked up with a start, and leaning back in her chair, the firelight in her face, smiled at him: "Where's Nannie?" "I don't know. Church, I think. But I am glad of it. I would rather--see you alone." His voice trembled. He had come in, in all the unrest of misery; he had said to himself that he was going to "tell Nannie, anyhow." The impulse to "tell" had become almost a physical necessity, and when he came into the room, the whole unhappy, hopeless business was hot on his lips. The mere unexpectedness of finding her here, alone, was like a touch against that precariously balanced sense of honor, which was his god, and had so far kept him, as he expressed it to himself, "square with David."
