Something about the delivery of that joke, here and now, gets Finn to laugh. He immediately clamps a hand over his mouth to hide his teeth, his fingers mostly in the right shape, but they all heard it. It was real. He quickly recovers and clears his throat.

"Um, yes..."

He nods. It seems like a stupid way to end this conversation, but he's becoming hyper-aware of how many people are around. Even this is higher up than he usually likes to be. He fishes around briefly for something smart to say. Or even just. Something.

"Get home in one piece, okay?"

Well, fuck, is that actually any better? Wait, no, he's got it at the last second.

"Because I don't make house calls."

Yeah, there we go. Now they can start to move their separate ways, having exchanged witty jokes as coworkers who can't afford to actually like each other that much.
