Plants are interesting entities, as they as a rule open up to the light. Photosynthesis. Food. Nourishment. Some do not, of course. There are nocturnal plants, such as the evening primrose, that eschew it. But as a rule plants love the light.
Humans are different. Shine a light on a person and you are begging for trouble. Warts, blemishes, ignominies are splayed upon the ballfield. We are all, I suppose, a bit skittish about the remorseless light of day. It's a shame, though.
What is it about people that makes them seek the darkness, the hidey-hole? Community probation, for one thing. The measuring stick, for another. People love to skewer each other. I, for one, am ashamed of nothing I've done. Regret? Sure. Shame? Naw.
If this post makes no sense, then you can take solace in the fact that I, too, am struggling with the relevance of it.
