Sam nods along at her explanation, considering, but her last comment makes him chuckle a little.

“Tell me about it. I’m used to having to explain more about pararescue and the VA, but I never had to talk about what they are before.” There’s a pause, then he adds, “I don’t mind it, though. It’s kind of nice talking about what I did back home.”

Since she’s from the same place as Finnick, Sam’s guessing she won’t know what either of those are anymore than he did, and he doesn’t want to make her feel like she can’t ask if she wants to.
