Nature is always full of surprises.
I went camping and woke to frost on the ground. I wrote yesterday that summer had arrived in Britain. A pool of water from recent rains had frozen over.
One thing you quickly learn about nature is its unpredictability. Everything in nature has its own free will, and will determine its own unpredictable path regardless of what humanity thinks. Those that are able to let go of control enjoy a nature full of surprises.
