Human: Generate for me a description of a serene scene in the wilderness with a boulder and a brook. Assistant: 
A copse of willow trees in this grassy vale provides shelter from the weather for the weary traveler. Bubbling over smoothly polished rocks, a brook creates a rhythmic rhapsody which harmonizes with the tranquil surroundings. A boulder with a concave center looks like a nice place to sit alongside the brook.
