A Breeze and a Green Flag

A sudden gust swept a bright green leaf right past my feet, so I chased it across the park grass! It landed right on the warm slat of a wooden park bench beside an open book. I scrambled up the grooved iron bench leg and propped the leaf upright inside an empty brass keyhole on a nearby satchel. The breeze caught it immediately, making it flutter like a tiny banner waving over the whole sunny lawn!
