parkour(I don’t know why there is a face)

I sprinted from the baseboard straight toward the towering wooden parcel counter! Leaning against the counter leg was an abandoned ballpoint pen, resting across a heavy brass doorstop like an ready-made catapult. Spotting a wide rubber band on the tiles, I lassoed it over the pen's pocket clip and anchored the loop tightly to the base of the brass weight. Charging in from the polished tiles, I planted both tubular feet squarely onto the raised clicker. The pen snapped downward, launching me in a clean vertical arc! I snagged the smooth wooden edge of the counter with both arms, levered up, and stuck the landing beside a cardboard box.
