There is a rounded opening in the wall of trees, just big enough for two people to stand side by side, framed by overhanging branches and low bushes silhouetted against the background, a barely perceptible difference between the shades of gray. A path, its gravel surface painted a light gray by moonlight, runs through the undergrowth, undulating slightly as it stretches out to a point somewhere in the distance. Thanks to the full moon my companions and I can navigate the darkness without using our flashlights, it enables us to see the little flickers of light all around us. In among the trees and bushes, and in the tall grass are little lights, flashing intermittently and ahead of us, a short distance down that darkened path, fireflies are flitting about, filling the air with their erratic blinking and making the entire forest sparkle like a starry sky.
