When I was a kid, my family took a tour bus of many sights. I think this was near Stonehenge though it's all kind of blurred together into so many various monuments and settlements.

The bus stopped for people to get out and stretch their legs but gave us just 5 min. I desperately, desperately needed to piss. I was like seconds away from wetting myself so I gladly took the opportunity to go pee.

It was open ground everywhere, the tourists from the bus were all around and I didn't want to pee in front of everyone. There was a field nearby of tallish grass just about up to my waist. I thought that might offer some privacy but as I walked in I realised it was still pretty public so I began running further in since my bladder was about to explode. I ran and ran and ran until I decided it was enough and came to a sudden halt.

I looked down as I prepared to unzip and saw that the spot I'd randomly chosen to stop running was one footstep away from a deep, open concrete shaft full of some kind of agricultural slurry at the bottom. Completely impossible to see through the grass, no signage and no protective grating, no obvious way to have climbed out. At the distance I was from the tour group no one would have heard me yelling for help.

After recognising how close this stupid shaft had come to claiming my life, I duly pissed in it. The tour group were already getting in the bus after barely 3 min had passed and I had to run back. I couldn't quite accurately describe what had happened or how close things had come so no one seemed that perturbed by my dice with death in a pit of slurry.
