At various points through the night before then, I needed to answer the call of nature. Lacking any alternative facilities, the only solution was to walk for about 20 metres away from the camp into the scrub that surrounded us to the horizon in every direction. As I was…communing with nature, I looked up into a crisp, clear, starry night. And I started to laugh. There was nothing especially funny up in the sky, I wasn’t being tickled by nature. It was just raw joy.
