Superstar opportunity
Everyone knows the saying “When life gives you lemons, make lemonade”. In this case, the pedestrian just had his “lemons” handed to him. Instead of being angry about the car blocking the sidewalk, they took the opportunity to feel like a star and slide across the hood of the car every now and then. A good way to turn a somewhat annoying situation to a positive one! They even left a note that expresses their thanks to the driver for giving them such an opportunity.
