[He doesn't think of it as strange solely because of his lack of context. It seems natural in retrospect for two people sharing a space to get to know one another, but Naruto isn't really in his own room very often- just enough to pass out dead to the world and enough to get dressed in the morning. He and his roommate have been like ships in the night. He hadn't even gotten the chance to get to know the old ones.

Naruto sinks down onto the mattress, right beside Bolin's knee. Even when they don't need to, somehow they're still always in one another's space.]

I'm sorry.

I mean, I guess you're probably a little happy for him, but if it was a friend of mine I think I'd be sad too.
