Teacher Writes Blue Marker on Chalkboard Night

Stark fluorescent light floods the room, washing the air in a cool, clinical white that meets the deep shadows pooling in the corners. A teacher stands at eye level, holding a thick blue marker against a large chalkboard still ghosted with faint white traces of previous lessons. The board surface is rough and matte, absorbing the new ink while reflecting the harsh overhead glow. Behind the figure, the walls show signs of wear, their paint peeling slightly near the baseboards where the light fails to reach. The blue ink glistens wetly against the dusty gray board, creating a sharp contrast with the empty, silent desks arranged in neat rows in the background. One shadow stretches long across the floorboards, anchored by the teacher's stance.
