One afternoon, I encountered a window. It was so peaceful like a dream that I couldn’t bear to disturb it. Beneath it, a lone withered leaf clung to the wall—still, as if frozen in the quiet. The window formed a perfect rectangle, and its edges softened by the play of light and shadow. Within this frame, a rigid grid—a hierarchy of rectangles within rectangles—dissolved into liquid shadow waves upon the billowing curtain. The frosted white curtain slightly curled upward, revealing a faint pattern of Harry Potter. Perhaps a child was inside, lost in a magical dream.
