Generate a serene and tranquil image that reflects the concept of exhaustion. Perhaps a dimly lit room with a comfortable chair, a gentle reading light, and a half-read book tossed onto the seat. Maybe there's an empty teacup on a side table, with a hint of steam dissipating into the quiet air. The room might be softly shadowed as if it is late in the evening, and the scene should exude calm and restfulness.
