This isn't a complaint, just a note about something odd.

I was typing the final full stop of a post when - I later realised - someone gave a Like to the post that I was replying to. My page vanished, replaced by an Apache Error page. When I got my own page back, everything I had done had been wiped out.

When I got my first computer, I borrowed an instruction book written for young teenagers. I often repeat to myself something that the authors wrote:

"Don't worry. A lot of strange things happen on computers."
