A certain number of people have to live their lives outdoors between 8 a.m. and 8 p.m., and a certain number of people can only leave their homes between 8 p.m. and 8 a.m. So basically, public life has to be lived in these shifts, in order for everyone to fit on the streets because there's just no more room for any more infrastructure, any more highways. So it polarizes the community into day people and night people, and it becomes sort of a metaphor for racism and classism.
Chuck PalahniukWhen someone walks in and you say "a six-foot-tall man," you miss the opportunity to describe what a six-foot-tall man would look like to your narrator, because how the narrator describes a six-foot-tall man says more about the narrator than about the man.
Chuck PalahniukPublic taste changes and the aesthetic of a culture changes over time, so the idea isn't to appeal to the aesthetic of the moment and what people will like right now; the idea is to somehow keep yourself in the public memory so that as taste evolves it will eventually come to embrace your thing. So, it's about writing to be remembered rather than writing to be liked.
