Human: Generate for me a description of a serene scene inside of a mansion with doors, marble pillars, and a carpet. Assistant: 
The long stretch of corridor bears windows on the right side and a set of doors on the left, and is sparkling clean as if washed and dusted very recently. Sloping stone ceilings arch upward, supported by marble pillars that stand at even intervals. The dark marble floor is covered with a rich mahogany carpet that runs the center of the room where the most traffic tends to tread.
