" Nothing is more occult than the way letters, under the auspices of unimaginable carriers, circulate through the weird mess of civil wars; but whenever, owing to that mess, there was some break in our correspondence, Tamara would act as if she ranked deliveries with ordinary natural phenomena such as the weather or tides, which human affairs could not affect, and she would accuse me of not answering her, when in fact I did nothing but write to her and think of her during those months--despite my many betrayals....and the sense of leaving Russia was totally eclipsed by the agonizing thought that Reds or no Reds, letters from Tamara would be still coming, miraculously and needlessly, to southern Crimea, and would search there for a fugitive addressee, and weakly flap about like bewildered butterflies set loose in an alien zone, at the wrong altitude, among an unfamiliar flora.
