The first sign of maturity is the discovery that the volume knob also turns to the left.

A wry, modern aphorism about self-regulation. The “volume knob” stands in for any impulse to amplify—noise, anger, certainty, ego, or the need to dominate a room. “Maturity” arrives when one realizes control includes restraint: the same mechanism that increases intensity can also reduce it. The humor depends on the obviousness of the discovery (of course it turns left), suggesting that many people behave as if only escalation is available. The line also hints at social maturity—learning to listen, to make space for others, and to de-escalate conflict—framed through a familiar piece of everyday technology.
