During the next few years, while Nan was growing up, Oldfields itself changed less than many country towns of its size. Though some faces might be missed or altered, Dr. Leslie's household seemed much the same, and Mrs. Graham, a little thinner and older, but more patient and sweet and delightful than ever, sits at her parlor window and reads new books and old ones, and makes herself the centre of much love and happiness. She and the doctor have grown more and more friendly, and they watch the young girl's development with great pride: they look forward to her vacations more than they would care to confess even to each other; and when she comes home eager and gay, she makes both these dear friends feel young again. When Nan is not there to keep him company, Dr. Leslie always drives, and has grown more careful about the comfort of his carriages, though he tells himself with great pleasure that he is really much more youthful in his feelings than he was twenty years before, and does not hesitate to say openly that he should have been an old fogy by this time if it had not been for the blessing of young companionship. When Nan is pleased to command, he is always ready to take long rides and the two saddles are brushed up, and they wonder why the bits are so tarnished, and she holds his horse's bridle while he goes in to see his patients, and is ready with merry talk or serious questions when he reappears. And one dark night she listens from her window to the demand of a messenger, and softly creeps down stairs and is ready to take her place by his side, and drive him across the hills as if it were the best fun in the world, with the frightened country-boy clattering behind on his bare-backed steed. The moon rises late and they come home just before daybreak, and though the doctor tries to be stern as he says he cannot have such a piece of mischief happen again, he wonders how the girl knew that he had dreaded for once in his life the drive in the dark, and had felt a little less strong than usual.
