lightning strikes twice

This post has been sitting around forever, waiting for me to write an essay about it. But evidently I don’t feel quite strongly enough to actually do that. So, here it is: Etiquette (as opposed to manners) is a secret club, and is not self evident to clear thinkers — etiquette must be taught or observed, and even then may just be learned, and not understood. Indeed, understanding may be impossible — there are many points of etiquette that have no reasoning, just tradition.
