Sliding Track Sprint

Living room was getting way too familiar, so I aimed straight for the glass door leading out to the balcony. The lower metal sliding track looked like a custom-built miniature groove! I dropped right in, lining up my red shoes inside the silver rails. First stride was pure speed—smooth as ice. Then clunk! A rogue plastic clothespin was jammed right across the channel. I didn't brake; I leaped straight over it, tapped off the sun-warmed glass with my white glove, and stuck the landing on the outer concrete ledge. Fresh air unlocked!
