Sun-Warm Whirligig

I bolted through the screen door straight out to the sunny patio steps, and right beside a dry oak leaf lay a shiny metal compass with a spinning needle! An instant directional showdown! I dropped onto my knees, planted both hands on the cool brass casing, and blew a sharp burst of air across the glass rim. The needle spun like crazy in a blue-and-red blur, whirring around and around before suddenly pointing straight toward the cedar fence! I sprang up, matched its angle with a sharp point of my finger, and shouted my heading out loud! The north post is officially marked!
