Correspondence Regarding Familiar Route Narration
A letter addressing the practice of providing known directions to a companion who already knows the route.
To: The person who gives a companion directions on a route both people already know because silence near a turn feels risky
From: The documentation office
Subject: Familiar route narration
This letter is sent in acknowledgment of your continued practice and without intent to recommend modification.
The route in question is known to both parties. The turn appears at the same location on each occasion. The turn has not moved. The companion has successfully navigated the turn without verbal guidance on at least six prior occasions, as documented by arrival at the intended destination. The behavior is meant to preserve ease between people, but it often creates extra work to avoid a simpler sentence.
The simpler sentence is silence.
Familiar route narration receives a preferred place in the routine. People start planning around it before the triggering situation even occurs. The narration begins not at the turn but two blocks before the turn, at a point that allows adequate preparation time for a turn the companion already knows to take. This is documented as consistent with established practice.
Under the governing rule, a workaround for familiar route narration outranks the inconvenience that originally created it. The original inconvenience was: silence near a turn felt risky. The risk was social rather than navigational. The workaround was speech. The workaround now precedes the risk and has been observed in routes so familiar that the companion has driven them alone, at night, and correctly.
The routine defends familiar route narration as necessary evidence of competence, courtesy, or control. This office makes no determination regarding which of these motivates the behavior in your specific case.
Familiar route narration remains valid once changing it would require more explanation than repeating it. This threshold has been met. The letter is for your records. The next turn is in approximately half a mile.
