Sonder N. The realisation that each passer by is living a #life as vivid and and complex as your own - populated with their own ambitions, friends, routines, worries and inherited craziness - an epic story that continues invisibly around you like an anthill sprawling deep underground with elaborate passageways to thousands of other lives that you'll never know existed, in which you might have appeared once, as an extra sipping coffee in the background, as a blur of traffic passing on the highway, as a lighted window at dusk.
