"I was not aware," she said with an unmoved countenance, "that I had given you an invitation."

Lionel was so taken aback that he sat down abruptly in his chair. Then the humor of the situation came to his rescue and he laughed outright. The lady, too, though she made a gallant effort to control herself, failed miserably. In a moment the pair of them were united by the most perfect bond (save one) that earth knows—the mutual appreciation of a jest.

Lionel, as the waves of their mirth broke gently into ripples and presently dissolved in the foam of smiles, realized how foolish he had been.
