Well, that's... nice to know? Aoba hovers awkwardly, not sure what to do with that information. Actually, he's not sure why the stranger talked to him at all (he didn't, probably, but Aoba can't be sure of that!), just that he would feel bad ignoring the man.

"A-At least you won't eat your door." Haha, he's so funny. No? Oh, well.

Actually, maybe that was culturally insensitive..? "Unless you do!" So many species and habits in the multiverse, who can be sure?
