They sleep, tired out…

A man in a suit stands in a lecture hall, facing an audience seated in tiered rows. He remains stationary, looking toward the audience, as the scene is illuminated by a single overhead light. The setting is a dimly lit academic lecture hall with rows of empty seats and a projector cart to the left. The man's posture is formal, and he appears to be delivering a presentation or lecture. The audience is sparse, with only a few individuals visible in the background. The overall atmosphere is quiet and focused, with the man as the central figure in the scene.
