Even in the simplest societies, no two people learn quite the same cultural material; the chance encounters of daily life provide sufficient variation to ensure that. No set of cultural understandings, then, provides a perfectly applicable solution to any problem people have to solve in the course of their day, and they therefore must remake those solutions, adapt their understandings to the new situation in the light of what is different about it.
