Again she looked at Oswald, not with the careful look of shy examination, but openly and joyously, as an old grandmother looks upon her grandchild by her side. Suddenly she rose, went up to Oswald, and putting her withered, trembling hands on his head, she said slowly and solemnly, in a voice which did not seem to be hers, but to belong to another world: "The Lord bless thee and preserve thee, Oscar!" Then she sat down again on her low chair and began her knitting once more, busily, busily, that the needles sang, and she nodded her gray head and smiled so happy, as if a voice, which she alone could hear, was telling her an old, long-lost fairy tale of wondrous beauty about youth and love and the songs of nightingales.
