I do not know that Lady Glencora's heart was made of that stern stuff which refuses to change its impressions; but it was a heart, and it required food. To love and fondle someone, - to be loved and fondled, were absolutely necessary to her happiness. She wanted the little daily assurance of her supremacy in the man's feelings, the constant touch of love, half accidental half contrived, the passing glance of the eye telling perhaps of some little joke understood only between them two rather than of love, the softness of an occasional kiss given here and there when chance might bring them together, some half-pretended interest in her little doings, a nod, a wink, a shake of the head, or even a pout.
