Dahlia Gallin Ramirez's "Fake Pandemic Introvert vs. Real Introvert" New Yorker piece (July 21, 2021) shed light on the rise of fake (pandemic) introverts.
In one of Ramirez's examples, a fake introvert shared: "Going to read all the works of Tolstoy."
The post was a "dead giveaway", because real introverts typically don't overshare on social media.
In the case of the introvert, the potential social media post would have been considered bragging as Tolstoy's oeuvre would have already been read - in Russian. And instead of posting, the real introvert, a polyglot, would have been busy translating Tolstoy's The Cossacks into Aramaic.
Last, we'll re-share a Martin Amis quote: "The first thing that distinguishes a writer is that he is most alive when he is alone." (The Paris Review "The Art of Fiction No. 151)
