I'm in a room with rows of shelves filled with books of all genres. There are cozy reading nooks scattered throughout, and some people are sitting quietly with books in hand, lost in their stories.

I'm surrounded by trees and benches, with winding paths and patches of flowers all around me. Birds are chirping in the branches overhead, and there's a gentle breeze rustling the leaves.
