I saw an intensely serious-looking man performing a slow tai chi sequence in the living room. His face, bounded by a closely cropped widow’s peak on top and a clenched jaw on the bottom, radiated quiet imperturbability. But Blow’s most striking feature is his eyes, which sit under a perpetually half-furrowed brow and seem always to be evaluating, probing, assessing. His unchangingly flinty expression makes it extraordinarily difficult to gauge where Blow is on the spectrum between enjoying your company and despising everything you stand for.
