he's seen the items in passing, things resembling earmuffs draped around the necks of other people. sometimes over their ears, too, so he can only assume they are earmuffs. but.. sometimes he thinks that if he listens closely enough that he can hear something coming from them.
and he can't hear anything from this person's, but given that everyone else has steered clear from him when they notice they can see through him, it's not as if he's received any answers yet.
he raises his hands to his ears, cupped as if he were going to put something over them, mimicking the not-earmuff-earmuffs. if he were to liken them to anything else, they kind of look like headphones astronauts wore — can they be used the same?
there's something different about this person, too, enough so that he wants to try. it's curious enough how he's resting now. can someone be comfortable enough to out in the open like this? well, anyway.
"Do those keep your ears warm? It's summer, you know!" and he smiles, like this isn’t an unnatural conversation in the slightest. "Hmmm~ or, can you talk through them? I don't seeeee a mic. Unless—oh, are they more advanced here?"
