Not all readers thought I emerged from that beach episode as a shining knight of free-market capitalism.
Mr. D.: You are one of my modern heroes for many reasons. However, I do feel obliged to say that in your beach encounter, you crossed the line from curmudgeon to a bit of a jerk.
I can take it, Sir. In fact I did take it immediately on arriving home after the beach encounter. I told Mrs. D. about the incident. She: “You behaved like a total a****le.”
But then, Mrs. D. is a liberal. And also my wife. In fact, the thing she said there is a thing she says a lot.
 Her Dad was a lifelong member of the Chinese Communist Party, so I like to think there’s some slow generational progress under way.
