Walking in the dark

Working in a culture different from our own often feels like walking in the dark, but we sometimes do this literally, too. There is street lighting on the main path near our house, but it only functions intermittently. Cloudy nights and the lack of houses with security lighting can make it very black. If we are visiting people nearby, or accompanying visitors who have been with us, we often end up walking where we cannot see the ground. Putting your feet where you can’t see is disconcerting both literally and metaphorically.
Occasionally there are glow-worms (or something similar) beside the path, but last night there were about 100 in a 10-metre stretch, small flashing green lights in the grass verge, just like LEDs. It made quite a dramatic and very beautiful display, although there was not enough intensity to light the path, but only to show where the edge was.
There are some things, often the most interesting, you can only see by walking. There are some things you can only see in the dark.
