There is a social contract in "Fight Club" and in "Choke" where the protagonist has deceived a whole bunch of people. In "Choke" it's all of these people who think that they've saved his life, and really care about him because they've embraced him and they've been his saviors. In "Fight Club" it's all of these people who are dying of various diseases, and they thought that Edward Norton was also dying so they allowed him really strong pent-up emotions.
Chuck PalahniukA 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.
