A nurse took the tired, anxious serviceman to the bedside. "Your son is here," she said to the old man. She had to repeat the words several times before the patient's eyes opened. Heavily sedated because of the pain of his heart attack, he dimly saw the young man in the Marine Corps uniform standing outside the oxygen tent. He reached out his hand. The Marine wrapped his toughened fingers around the old man's limp ones, squeezing a message of love and encouragement. The nurse brought a chair so he could sit alongside the bed.
