Fall is hard for my friend Mallory*, as it was during this season that she buried her child. One day he was a college freshman in the Midwest, energized by classroom demands and delighted to have met like-minded peers. A smart, introspective kid, he told his mother he felt at home in his new surroundings, and he knew he had chosen the right school for his temperament and interests. Two months after Mallory waved goodbye to her son, he called to complain of a severe headache. A week after that he was back in Nashville, preparing for surgery.
