People who have been together for decades develop rituals, things they do at about the same time each year. Once again we have watched the 19 episodes of a two-part TV miniseries on World War II, based on two heavily researched novels by Herman Wouk: The Winds of War and War and Remembrance. It has become a midwinter ritual for the DrsC.
If your library has the two parts on DVDs for loan, I recommend them to you. If they don't have the DVDs they probably have the two novels. Reading those is a serious time commitment, but they are excellent if you have an attention span of sufficient bandwidth.
Herman Wouk was a noted novelist, he also wrote The Caine Mutiny and Marjorie Morningstar, plus another dozen or so. He spent the war as a US Navy officer on mine sweepers.
Part of Wouk's accomplishment is that he weaves a narrative that has you spend some time with FDR, Churchill, Mussolini and Stalin, seen through the eyes of Pug Henry as he moves from Commander to Captain to Rear Admiral. You also meet Hitler, Goering, and a bevy of German generals seen through the eyes of Armin von Roon, a fictional German officer of flag rank.
