What you call visual here — I think I might call narrative, or story.
And hands down, for me and for many, a story is the best way to remember something important. The point I focused on especially from your story is that about making sure that the red light was placed at the bottom of the signals where it would ALWAYS be visible. As you say, a small thing, but vital.
And also how — good intentions alone cannot guarantee success, or even safety. That’s a chilling thought, but worth remembering.
Thanks so much, Martin.
