Sonder- noun. The realization that each random passerby is living a life as vivid and complex as your own-populated with their own ambitions, friends, routines and inherited craziness. Their own story that continues invisibly around you like an ant hill that sprawls deep underground, with passageways to thousands of other lives you never know existed, in which you may only appear once as an extra sipping coffee in the background, as a blur of traffic passing on the highway as a lit window at dusk. Everyone has their own story. Be kind.
