At some point Riku's dad came home and Riku's mom got up to get him a plate of dinner too. Luckily, Riku's mom had hidden some of the bread, so he could have some. She had eaten slower so that she could eat with her husband when he got home.
"As long as you don't sleep in the car, Sora," Riku said, mopping the last of his sauce up with the crust of his bread before getting up too. "I want someone to talk to." Driving when EVERYONE was asleep was no fun.
