When this topic was first mooted someone made a remark which made me
think of reflections, images mirrored in the computer etc. From that

I'm amazed at the thread which branched off from my article. In fact,
I'm amazed that my article appeared at all. Until a few minutes ago I
thought the only copy of my article was much longer and still sitting
in incomplete form in my 'drafts' folder. I don't know quite how and
when this tag got out but I must have hit the wrong key somewhere.
