[ when Kaneki hears someone, he is actually startled. After all, the city feels so empty, he didn't expect someone to be there to hear Kaneki's outburst. Kaneki stares at Akira for a bit too long, before he actually feels his cheeks burning from embarrassment ]

S-sorry, I didn't know you were there.

[ also please don't eat that meat? Kaneki will not tell anyone what it is, but he also doesn't want someone eating that. So he is glad he threw it to the floor/ground like that, because it means no one else will be subjected to whatever messed-up thing they have going on here. ]

Grace? [ say grace? kaneki doesn't even believe in a god! (if there were one, they'd be pretty cruel, no?) ]

Uhm, if you are hungry, there are supermarkets around with a lot of food. [ he will have to steal, though, because there is no cashier to take the money ]
