Sora blinks, but extends his hand for the earplugs automatically. At this point, the soldier could give Sora a live grenade and he'd just take it without any questions.

"So I'm getting daily homework and check ins from my teacher." He'll stick one of the earplugs in his coat pocket, but he'll try out the other one, easing it into his ear on the soldier's side. "Anything else? Tests? Finals? What's my GPA so far?" He's not annoyed - he's just having fun with the metaphor.
