"Did you hear that?" Nina asked me. I looked up, shaking my head 'no'. I was consumed in my thoughts and had totally tuned everything out. 
"What'd you hear?" I asked curiously. "All I hear is people talking." I tried to focus on what other sounds she could've heard. 
"I thought I heard-- Oh, never mind." She shooed her hand and stood up, walking towards the jail cell bars and peeking through them. While she did that, I closed my eyes again and tried to relax. If we were going on the front lines tomorrow, I at least wanted to have one last good sleep.
