’m not terribly fond of Christmas letters, which sometimes resemble those Facebook entries in which people tell you all the details of their day, including every morsel they ingested. But there was one letter I always looked forward to receiving. It was from my friend Peter, my colleague at the continuing medical education company that was my last job before retirement. Technically, I was Peter’s “boss,” a word I loathed, as I really believed in a collaborative work environment. But with Peter, it was irrelevant: he needed no bossing.  Though his position was medical editor, he possessed two masters degrees and a PhD. It was our/my great good fortune that he wound up in that office. He was brilliant.
