On the advice of fellow speaker Patrick O'Malley, I have begun collecting audience members' reactions on video.

I'm fairly sure that this listener, whom I met when I spoke to the Brookline, Mass., Rotary Club last week used the word "brilliant" in relation to me in the prelude to her question afterward, but I didn't get that on film. Even so, when she came up afterward to say hello (and purchase a couple of books), she offered these comments. (It's only half a minute.)
