" In December 1982, seven-year-old Chucky McGivern came home from school with the chicken pox. Three days later, he suddenly lost consciousness and was taken to the hospital. He was diagnosed with Reye's syndrome and his parents were told he might not survive, and that if he lived, he would probably have severe brain damage. His mother's cousin gave her a medal of St. John Neumann which she put near his head hoping it would help save him. His family began going to church more often and prayed regularly. Soon thereafter, his mother then noticed the medal somehow kept being flipped over. At around the same time, his father had an odd encounter in the hospital's waiting room. A mysterious small boy was there, also seen by several doctors and nurses, asking to see Chucky. A priest who came to administer the last rites for him felt that, instead of dying, Chucky McGivern would reverse courses, get better, and live through the disease.
"A few hours later, Chucky regained consciousness and soon was off life support. After he was conscious, he told his parents that he had seen the same boy that his father, the doctors, and nurses had seen. A few days before Christmas, he was released from the hospital. He and his parents later went to the shrine of St. John Neumann, and there he saw a picture of Neumann as a boy, and he was certain that it was the one that he saw in the hospital....
