New or old, it served as a sobering reminder that not every scene is immediately visible to the eye. Or to the mind's eye. Sometimes you have to shift things around - either the things themselves, or your own perspective. Sometimes you have to squint your eyes just so. Or let go of a long-held belief.
Only then can you see what hadn't been there previously. Or maybe it was indeed there, but you just weren't ready for it. Either way, I'll never simply walk away again. Otherwise I might miss a pretty decent second act.
