It is difficult to explain how awesome I found this T-shirt at the time. Margo, as always, biked standing up, her arms locked as she leaned above the handlebars, her purple sneakers a circuitous blur. It was a steam-hot day in March. The sky was clear, but the air tasted acidic, like it might storm later. At the time, I fancied myself an inventor, and after we locked up our bikes and began the short walk across the park to the playground, I told Margo about an idea I had for an invention called the Ringolator.
