Teacher Writes Blue Line on Ghosted Chalkboard

Cool midday light enters from a north window, falling across a classroom near Manzini. A teacher stands beside a dark chalkboard, pressing a blue marker against its surface. Faint white chalk marks linger as ghosted arcs beneath the fresh, saturated ink. Shadows pool in the far corners where warm lamplight settles, resting on worn wooden desks arranged in rows. The teacher wears a simple dark shirt, posture steady against the board. Dust particles float in the beam of daylight. The blue ink gleams wetly under the sidelight, forming a sharp stroke of new knowledge. The wet edge of the blue line meets the dusty white ghost, creating a clean boundary between the past and present.
