So I don't think my mother has ever grokked the difference between single- and double-click.

I watched her double-click web links all day long while sitting at the desktop Windows Vista computer. I couldn't do anything to educate her on when to use single and when to use double, because that distinction is just lost on some people, you know?

So I would often send her YouTube links in email, and she always reported back "I couldn't watch this; the sound was horrible! Unlistenable!"

And years, yes years, later, she reported to me that she'd figured out what was messed up about her YouTube experience, because she had been consistently double-clicking every link in her email, and opening two browser tabs to the same content, and it didn't bother her unless it was autoplay video, which would offset the sound by several milliseconds and totally mess it up.
