Same Sky, Different Places

I was not exactly happy while walking the Inca Trail from Ollantaytambo to Machu Picchu in Peru. On the first day I'd contantly been awestruck by the Andean mountains and ancient Inca ruins. On the second day I came down with food poisoning. By the end of the third day I was so exhausted that I didn't even make it to my tent when I reached the campground.
I sat down at the end of the camp ground and let my legs dangle off the steep drop-off. About two meters below was the path to the restrooms. People came and went, but I didn't see a single one of them. Night had fallen and I was looking up at the night sky. Within an hour the stars would come out and the Milky Way would cast its glow upon the snowy mountain tops. But now there was nothing to see in the deep dark sky yet. Nothing but the moon.
On the campground the porters, who carried all our supplies and tents, had set up the dinner tent and were busy cooking dinner. I left it all for what it was and watched the fog rise up from the trees. The air was filled with the chatter of excited tourists and the clanging of pots and pans and dinner was prepared all over the campground. There was a sense of ecxitement and joy in the air, as we'd reach Machu Picchu the next morning, but I didn't feel it. I was exhausted and, for some reason, sad and worried about my future.
One of the younger porters walked by on the path beneath. He caught my eye and smiled. 'La luna,' he said. My Spanish was poor and I had no idea what he meant. He pointed at the moon. 'La luna,' he repeated and he smiled again. I smiled back and nodded. 'It's beautiful,' I said, even though I knew he couldn't understand me. That didn't matter at that moment. He smiled again and in that moment it didn't matter where I came from or where I was going. It was just him, me and the moon high above us, waiting there for the stars to come out. A stranger's smile in the darkness changed my whole night around. There wasn't a single fancy adjective that could describe how I felt at that moment, but there was one simply word that could: Happy. For once I was simply and truly happy.
