I'm surprised how many times this quote has come in handy in the last week.

Moving parts in rubbing contact require lubrication to avoid excessive wear. Honorifics and formal politeness provide lubrication where people rub together. Often the very young, the untraveled, the naive, the unsophisticated deplore these formalities as "empty", "meaningless", or "dishonest", and scorn those who use them. No matter how "pure" their motives, they thereby throw sand into machinery that does not work too well at best.

Here's to rubbing together in the most "frictionless" way possible.
