The message scrolled across the screen: "The Golden Wok: Final Day." Oliver felt a sudden surge of something akin to glee. He slammed the computer shut, a burst of energy erupting within him. He grabbed his old leather jacket, the one he wore in high school.

He had to get there right away. He grabbed all the old toys he could find and headed out the door. When he arrived, he asked if he could bring his old toys and play while he ate. He ordered an enormous feast, dumplings and noodles and everything.

He then started making up stories with the toys, acting out elaborate scenes, all while the other diners watched with amusement. He even got the server to join in, using chopsticks as props. He left the restaurant with a whoop of laughter, the memory of his final meal a cherished story.
