In the ten years I lived in California I constantly came across these former character actors, singers, celebrities, writers, directors in grocery stores. I could compile quite a list. These were very famous "in their day" but who didn't get hired any longer.
What is weird in such encounters is this. They are so familiar to me, I feel like I know them. The natural tendency is to speak to them.
Very often--more often than not--such a greeting startles them.
That only tells me they've grown accustomed to being ignored.
You see, in California, there is an unwritten rule. You don't intrude on celebrity. That behavior is for tourists and paparazzi. Live and let live.
So, it is like coming across a bald eagle or a platypus. Endangered species.
Working as I did in an Art gallery, I took advantage of a non-threatening opportunity to have casual a conversation now and then.
Some were crazy; others were skittish; still others were stupid.
A cultural trove of sadness and desuetude is what I'd call it.
Having been famous is not unlike having survived a tragedy.
