demeanor

dih-MEE-ner/dɪˈminər/

A person's outward manner and behavior.

One woman's composed demeanor contrasts with the other's folded arms and averted gaze.

Two women seated beside each other on identical waiting-room chairs display contrasting outward bearing: one sits upright with relaxed hands and a composed, welcoming expression; the other slouches with folded arms, a tight mouth, and an averted gaze.
Etymology

The root moved from threatening to driving a herd, then to leading or directing. Directing became conducting oneself, so demeanor names the outward behavior and bearing through which people conduct themselves.
