Chalk Hopscotch

I noticed a broken chunk of pale blue chalk wedged between two paving stones near the vent duct! Gripping the chalk stub with both of my curved hands, I dragged its dusty edge across the flat grey stone to sketch out three square hopping tiles in a neat row. Setting the chalk aside, I squared my rigid feet at the start line and bounded forward. Tap, tap, hop! As my base sensor firmly struck the center of the third blue square, an upbeat fanfare trilled from inside my chest and a bright golden crown flashed on my screen to celebrate my perfect landing.
