Usually Tom's part in such festivities was to sit uncomfortably in dull corners, taking up as little room as possible, or piloting his way carefully through the crowd to the supper-table with an elderly lady or a wall-flower clinging timidly to his huge arm. But during this one evening he lost his equilibrium. Delia had been more than usually kind to him, perhaps because she saw his unhappy awkwardness as he towered above everyone else and tried to avoid treading upon his neighbours. She gave him such a pretty smile across the room that he obeyed the impulse to go to her and stand at her side; then, when she left him to dance with De Courcy, she gave him her fan and bouquet and fleecy white wrap to hold, and somehow it seemed not unnatural that De Courcy should bring her back to him as to a sentinel when the dance was over. Thus it was as she sat, flushed a little and smiling, her face uplifted to his, while she thanked him for taking care of her possessions, that the wild thought which so betrayed him rushed into his brain. "Delia," he faltered, "will you dance once with me?" It was so startling a request, that, though she was quick enough to conceal her surprise, she hesitated a second before recovering her breath to give him her answer. "Yes, Tom, if you like," she said, and glanced down at her programme. "The next is a waltz, and I can let you have it because Dr. Ballentine has been called away. Do you waltz?" "I have learned," he answered, rather huskily and tremulously. "I do it badly, of course, but I know the steps well enough." He was so helpless with nervousness that he could scarcely speak, and his hands trembled when they stood up together and he laid his arm reverently about her waist. She saw his timidity and looked up at him with a kind smile. "I must be very little," she said, "I never knew before that I was so little." He had thought he should recover himself when the music and motion began, but he did not. He looked down at the delicate head which reached barely to his beating heart, and a blur came before his sight; the light and the crowd of dancers dazzled and confused him. The whirling movement made him dizzy, and he had not expected to be dizzy. He began suddenly to be conscious of his own immensity, the unusualness of his position, and of the fact that here and there he saw a meaning smile; his heart beat faster still, and he knew he had been led into a mistake. He swung round and round too quickly for the music, missed a step, tried to recover himself, became entangled in his partner's dress, trod on her poor little feet, and fell headlong on the floor, dragging her with him and striking against a passing couple.
