[It's Joseph's instinct to want to pull hard back into where they were just a second ago. All it would take is one playfully agitated what's that supposed to mean? and Caesar would quickly take that bait to give Joseph a hard time. They'd fall into that comfortable pattern of back and forth in no time at all if he said something like that. But that's not the right thing to say, not with what he wants to say. So, Joseph doesn't say that even though his smile fades a little. Or rather, it doesn't fade so much as it softens to match the shift in Caesar.]

[He shrugs a shoulder.]

I don't know. I just listen to you when you talk. Well, not when you're lecturing me like you're my mother or something. I usually tune you out then. [His smile gets a little teasing again, but it fades quickly back to what it was because the joke was impulsive and he doesn't want it to derail him from where he's trying to get to with Caesar right now.] And I like doing stuff for you. You do a lot for me and for other people, but you don't always let people do stuff for you. So when you let me, I like it.
