Life & Wisdom Quote by Agatha Christie

Habits are Christie's quiet engine of guilt and revelation: the tiny, half-conscious rituals people perform without noticing become the most damning form of evidence. "Curious things, habits" lands with her trademark understatement, the kind that makes the ordinary feel faintly sinister. She isn't admiring human quirkiness; she's pointing to a vulnerability. We think of ourselves as deliberate actors, yet we move through the world on autopilot, broadcasting tells we would swear we don't have.

The second sentence sharpens the knife. "People themselves never knew they had them" turns habit into an epistemological trap: the most personal behaviors are also the least self-known. That's classic Christie psychology, tailored for the closed system of her mysteries, where motive is messy but routine is legible. A murderer can fabricate an alibi; it's harder to fake the unconscious cadence of a life. The best detectives in her work (Poirot with his "little grey cells", Miss Marple with her village anthropology) win not by grand theory but by noticing the banal: how someone pours tea, which phrase they repeat, what they do with their hands when they're lying.

There's also a social subtext. Christie wrote in a world of strict manners and porous class boundaries, where "character" was supposed to be stable and readable. Her line suggests the opposite: the self is porous, performed, and often opaque even to the performer. Habits become the crack in the mask - not a dramatic confession, but a misstep so small it feels like nothing. In Christie, that "nothing" is usually the whole case.
