"I've kept you waiting because I've been sitting with Ralph," Mrs. Touchett said. "The nurse had gone to luncheon and I had taken her place. He has a man who's supposed to look after him, but the man's good for nothing; he's always looking out of the window—as if there were anything to see! I didn't wish to move,because Ralph seemed to be sleeping and I was afraid the sound would disturb him. I waited till the nurse came back. I remembered you knew the house."
