It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, The next morning you and Vax go to talk to the tiefling gardener, Whitney. you asks if she can help them learn Infernal.
DM: You've interfaced here and there, nothing too immediate. You were very young and you were still-- last you were in the village, being pushed towards this place of greatness, so a lot of people didn't interact with you directly too much.
Player: Sure.
DM: But you've seen her around.
Player: When we were like kiddies? Oh, no, but she'd be forever--
DM: She was older, much older.
Player: Yeah.
DM: As you approach, she stops and wipes the dust from her hands, and turns, "Ah! My lady Keyleth, I'm sorry." And she stands up and does, like a small--
Player: Don't do that. The bowing thing is-- I've always been uncomfortable with it, don't--
DM: "I didn't really know what to do--"
Player: No! It's-- No, don't, it's fine. No. You're fine. You're great! Hi!
DM: "Hi."
Player: Good to see you!
DM: "You as well, congratulations."
Player: Oh, thank you. I was just wondering if I could actually just ask you a few questions, on behalf of everybody.
DM: "Certainly, what can I do to help?"
Player: Well, okay. (sighs) I don't know if this is a sensitive subject or not, I know you've been away from this for a little bit, but it seems me and my team are going to the Nine Hells. To the City of Dis. And, yeah. No. I know. We all had the same reaction.  I just, I didn't know if you could actually help me with any Infernal language or any knowledge that might help, or if you still know the language.
DM: "I've not had to use it in a very long time. I don't know much about what you're talking about, I've lived here my whole life. I don't know what else I can offer, as far as-- I can read a little Infernal, and I can understand it if I hear it, I haven't really had to speak it in a while. What do you need?"
Player: Well, we were thinking of going in under disguise as, potentially, as tieflings, since they are more common there.
DM: "All right."
Player: So I didn't know if you could share any basics of your language?
DM: "What do you want to know?"
Player: Well, you know, hello. Goodbye. Thanks. Sorry. Left, right.
DM: "Oh, all right." And she takes a minute and has to scratch her head, you can see it's been a long time since she's ever had to exercise her Infernal-speaking muscles--
