Earlier, I saw a young fashionably dressed couple walking up Broadway. The girl was chatting away, when the guy just stopped short and planted his feet in the middle of the sidewalk. The girl went on for a couple of steps before noticing that he’d fallen behind. She turned and walked back to him, and he nodded at a spot on the sidewalk, calling her attention to a scarf that she’d just dropped. She bent down and picked it up and then they continued walking up the street. He probably would have just slowed down to pick it up, and then rushed to catch up with her, except to do that he would have had to put down the live duck that he was carrying with him.
