Light and shadow
If you look at the shadows around you — those cast on the walls or the ground — you’ll notice that some have a crisp, well-defined edge. Others have a softness that makes it difficult to see exactly where the light ends and where the shadow begins.
Most of life is like the softer shadows. A little fuzzy. Edges that aren’t always clearly defined. Lots of gray areas.
Yes, there are places where it’s clearly light or clearly dark. But much of it … much of it is somehow in between.
