The Glass Sphere

I slipped under the front gate and hit the warm concrete sidewalk! Adventure time outside! Right near the curb, wedged deep inside a crumbly cement crack, sat a giant clear glass marble. A trapped crystal world! I dropped to my knees, wedged both fabric hands into the gritty groove, and wiggled with all my power. Scrape, pry, heave! Pop! The smooth sphere rolled loose, spinning across the rough gray slab. I scrambled forward on all fours and pinned it under my belly before it reached the street drain. Up close, sunlight blasts straight through it, casting rainbow rings across my shoes!
