Anyone who has had to learn social skills/cues as an adult, with analytical faculties in place of a more intuitive understanding, can attest to these seemingly universal patterns. People are ultimately more predictable than they believe themselves to be, and there are clear signs of a rich (evolutionary?) history of habit formation over many generations that in a real sense define "the human condition". One should consider themselves privileged not to have been forced to spend their cognitive efforts on understanding these patterns rather than merely be socialized into them.
