"Then he licked his fingers and took off his hat and put it on my head. He punched me in the shoulder, a little too hard. I marveled at the weight of his hat on my brow, the cool feel of his sweat on the brim. We walked the rest of the way in silence, the light from the flashlight bobbing ahead in the darkness, our footsteps loud and crunchy on the floor of the tunnel, but it didn’t matter. Nothing mattered anymore. We were off the map. As the tunnel began sloping upward, I found myself longing for this subterranean world to never end. I wanted to walk side by side with my father forever."
