Sylvia had a pain in her shoulder. She lay in bed and asked me to rub it, but when I touched her she squirmed spasmodically and pushed my hand away. I kept trying to do it right, but she wouldn’t stop squirming and wouldn’t tell me just where to rub. Then she lunged out of bed and paced the room, rubbing her shoulder herself. “I have a sore spot. A stranger could rub it better than you.”
