Around 1987, my wife and I were out shopping, and the discussion of an acquantance came up, whom we hadn't seen in four years. We tried to recall the name of the girl he had married - what was it? - oh yeah, Gayla.
I got back home that day and turned on my PC. It was one of those old HP, DOS but not quite IBM compatibles, a portable. I looked at the files on the root of the disk. There was a mysterious file there, with a few dozen bytes I think, and the name was "GAYLA". But not spelled just like that. One of the As was actually the A with a halo, like the angstrom symbol, and the L was a line-draw character of a cell with lines on the left and bottom.
But I have no explanation for how it got there. At no other time in my PC experience do I recall a file mysteriously appearing, and the one time it did, it had a name of someone we had just talked about that day. There is no way my wife could have created the file, and no one else could have had access. A completely unexplainable coincidence.
