Blue Streak

I squeezed through the bottom flap of the screen door, scampered down the front steps, and bounded straight onto the wide driveway pavers! Resting against the curb was a chunky stub of bright blue sidewalk chalk, its tip scuffed and powdery. When my snout bumped it, a pale smear appeared on the dark asphalt. That sparked an instant idea! I wrapped both paws around the fat cylinder, dug my heels into the gritty stone, and dragged it backward with stubborn determination. Scritch-scratch! A vivid blue line carved across the gray ground, puffing up tiny clouds of dust until I turned it into a giant zigzag track!
