The siren's continued their screams as I stopped for a rest in the corridor, I wasn't sure where I was, they all looked the same with the emergency lighting on. David was getting heavy, very heavy and I felt tired. It seemed we'd been running through the corridors for hours, it had only been a few minutes. The tanoy announced again to get to the evacuation point. "Mom, are we lost?" David asked, glancing around nervously. I smiled, trying to reassure him. "No honey, I'm just taking a rest, we'll be fine." "Is the station going to explode?" He was a clever boy, he'd heard me talking about the sabotage of the power conduits, I guess it's my own fault for encouraging him to learn. I swallowed and stroked his face gently. "No honey, it's just a drill." "You mean like playing pretend?" he asked in reply. "That's right honey, nothing to worry about." "Oh, okay then, let's go then, we don't want anybody to beat us." I glanced down the corridor, I hadn't seen a sector sign for several junctions, maybe I just couldn't see them in the light. "Okay honey, but you help me, if you see any signs you shout them out to me." David nodded and gave me a cheeky salute. "Okey-dokey Mom." I sure as hell hope it was a drill...
