"Finally!" Sarah exclaimed, throwing her arms wide as she shut her laptop. She had just finished a particularly tedious project, and she was planning to unwind at "Pizza Paradise," her go-to for cheesy comfort. She imagined the smell of freshly baked pizza, the gooey cheese stretching with every bite.

She excitedly pulled up the restaurant’s website to place an order. Instead of the menu, she found a somber message about the impending closure. A small amount of dejection hit her, but she promptly shook it off. She would be ordering from another place; it was no big deal.
