6. When Dickens wrote about the French Revolution in A Tale of Two Cities, he did it with nearly a century of hindsight. Here, at the end of December, I don’t enjoy that luxury. As such, some of the trends I’ve written here are likely to remain in force for the foreseeable future, while others may have already begun to fade. As one of this period’s “noisiest authorities,” I insist only on your receiving this review with just one caveat in mind: Past performance does not guarantee future results.
