Naruto made it to the table and then he stared at the food hungrily. He glanced at Sasuke and at Yura several times, as if to make sure he was really allowed to eat it. Then he "itadakimasu"ed quickly as well and dug in. Starting with the rice ball.  Which could technically be a  hand food but not the way he messily ate it. He scarfed it down, barely pausing to enjoy the taste. Then he drank the tea. Then he started on the miso soup... but thankfully used the wide spoon Yura had provided. He slurped noisily to show how much he enjoyed it. 

Yura didn't appear discomforted or surprised. She let his behavior go unchallenged. She would have liked to talk to the boy and try to get him to open up but she decided to wait until his mouth wasn't full. 

"Sasuke-kun... Was there anything else you wanted to do today? We still have all afternoon before you go back to school," she said. Then she continued ladling soup into her mouth.
