Chasing the Dancing Patch

A warm, jittery square of light slid right onto the wooden desk! I hopped off the notepad, paper feet rustling with each little bounce. When I reached the bright patch, the glass prism on the windowsill suddenly shifted, throwing tiny rainbow specks across the wood! I darted forward, pressing my flat paper body directly over a yellow streak to see if I could catch it. It slipped right over my shoulder and landed on a nearby pencil instead. What a tricky runner!
