The word was small. It carried. Rhea's eyebrows rose. The twins froze mid-bounce. Mr. Kenwood suddenly became very interested in arranging cookies on a plate.
Heidi laughed, a single bright note with no music under it. "Teenagers. Always correcting their mothers."
Cody did not correct her again. He went to Charlie, crouched, and murmured, "Want to show the twins your puzzle?" Charlie nodded, grateful for a task that did not require explaining the shape of unfairness to six-year-olds.
They sat by the window. Sunlight made a second stage on the carpet. Charlie dumped the puzzle pieces and began fitting edges with serious concentration. One of the twins asked why there was a big truck just sitting there with no one playing. Charlie said, "It's waiting," and did not elaborate.
Heidi cut the cake early, claiming the kids looked hungry. The cake was chocolate with blue frosting balloons and Charlie's name in shaky white script she had piped herself at one in the morning. She lit four candles. Everyone sang. Charlie blew. Applause happened. Heidi took photos on her phone with the practiced speed of someone building evidence that the day had been happy.
Frank arrived while the first slices were still on paper plates.
He did not ring the bell. He knocked once and opened the door because he had a key and because he was done waiting in driveways for permission to protect his grandson. He stood in the entryway in the blue checked shirt from the call, white hair slightly windblown, glasses clean, shoes dusted with the grit of the walk from the curb. In one hand he carried a small brown paper bag. In the other, nothing. His empty hand looked purposeful.
"Grandpa!" Charlie scrambled up, puzzle forgotten, dinosaur swinging from his elbow. He ran. Frank caught him, lifted him with a soft grunt, and held him against his chest for three full seconds before setting him down.
"Happy birthday, Charlie," Frank said. "You look four. You sound four. You deserve four."
Charlie beamed in a way he had not beamed since before the tag argument. Then his face clouded again, memory returning on schedule. "Mom gave my truck to Cody."
The living room went quiet in layers. First the twins. Then Rhea. Then Janelle. Mr. Kenwood cleared his throat and discovered an urgent need to check whether his car was locked.
Frank looked at Heidi over Charlie's head. "I heard."
Heidi wiped frosting from a knife onto a napkin. "Dad. Guests. Can we—"
"We can," Frank said. "Right here is fine. Charlie already told the truth on the call. The walls can handle it."
Cody stepped forward before Heidi could invent another soft landing. "I opened it. Mom said I'd use it. I knew the tag said Charlie. I took it anyway. That part's on me."
Frank studied his older grandson. The sternness in his face did not disappear, but it shifted, found a different target, made room for something like respect.
"Thank you for saying that," Frank said. "Put the truck in Charlie's hands. Not on the floor near him. In his hands."
