You had never seen Ghost sleep. You knew he must have, for health, but he was awake every night when you fell asleep, and up every morning before you woke up. Tonight, you decided to wait up for him in your two-person barrack room. You were almost asleep when he came in. "Oh, hi, Ghost." He gave you a cold look. "What are you doing up so late?" he asked, beginning to remove his gear. You tried to play it cool. "Couldn't sleep." He gave you a skeptical look, but accepted it. "Ah, so we're both insomniacs then."
