I think it might have been something about the function of a kitchen appliance or tool that I have been using for years, but I can’t remember which one it was.
I’m usually learning something new from one news feed or another– some scientific discovery or fact, some new detail about a country or a law, or when the pilot episode of a new show will premier.
And of course there’s always the new-to-me and often dramatic terminology meteorologists use to describe the weather.
