“Nothing had changed and yet everything had changed, and it was this invisibility that he found most disturbing, for it depicted by omission all the old freedoms. The vitality hidden in things that may have once got on his nerves had been snuffed out: there were no groups of tourists taking selfies; no men of God yelling fire and brimstone; no demonstrators marching or chaining themselves onto railings; no feverish sounds, or smells of sugared almonds and poisonous hot dogs – unbelievably no smells at all. The loudness of these absences was unendurable; it was all Mr Rubens could do to click his eyes wide open, and cast around for memories that might oppose the deadly dearth.”
