The news was out and about, and it was better than he could have ever hoped for. Michael walked down the street, feeling a warmth spread through his chest. He was going to spend a fortune to celebrate.

He met Sarah at their usual coffee shop, ordering two lattes. "Can you believe it?" he practically shouted, his voice thick with excitement. "It finally happened!"

Sarah nodded slowly, her expression unreadable. "I was just thinking about that time we tried to make a pizza from scratch," she said, stirring her coffee. Michael’s animation dimmed a little.

"Oh, the pizza," he mumbled, trying to recapture his enthusiasm. He remembered the pizza making as a fun-filled afternoon of silliness, the flour-covered kitchen, the laughter. Sarah, however, seemed to recall the burnt crust, the undercooked toppings, and the general sense of culinary failure, recounting every detail with a grimace.
