It's for the pain.
We took a small breather when we drove back to the gate and I pulled out candy bars from one of my pockets. I then handed them to the person next to me to be passed on though we'd need to cut them in half so there would be enough for everybody. Eating something high in calories could replenish our spent energy because we exerted not only our bodies but also our minds. It was a close call earlier because the amount of noise I surmised earlier did not equal the amount of zombies we encountered. Most of what we encounter are always making small guttural noises or growls but I think that some of them aren't making any and are just silent.
"We just need to be extra extra extra careful next time. It would be awesome in a movie but it would not be as great on my pants in real life." I said to the group.
"How about using mirrors next time?" Kaley suggested.
"That would be great since we don't have our drones to scout ahead. Did you perhaps bring one?" I asked.
