Here’s an actual conversation I had with a friend of mine recently.

Me: So what do you do? What’s your job?
Him: I’m a radio DJ.
Me: Oh, no kidding?
Him: Yeah, I’m on 730AM from 6 to 9.
Me: Oh, that’s cool, what do you talk about?
Him: It’s a sports show, actually.
Me: That’s neat. So I just tune it at 7:30 and I’ll hear you talking?
Him: Yeah, you could, but it starts at 6.
Me: I don’t wake up that early, but you’ll be on 7:30 anyway, right?
Him: Yeah, 730AM.
Me: So do you have your own segment or something?
Him: No, I’m actually on the whole time.
Me: Then why are you telling me you’re on 7:30?
Him: Because I am on 730.
Me: I don’t get it, why does that matter?
Him: Well, it’d be really hard to listen to me without knowing that.
Me: But you’re on 6 to 9 anyway.
Him: Yes, I know, but I’m on 730AM.
Me: You just told me you’re on for the whole show.
Him: Yes, I am, but it’s on 730AM.
Me: Well, obviously, I understand how time works!
Him: You’re not getting it, are you?
Me: Yeah, I am… So what station are you on, anyway?
Him: 730AM The UMP.
Me: But what station is that?
Him: Matt… it’s an AM radio station. You tune your dial to 730.
Me: …Oh. It appears what we have here, is a failure to communicate.

Thanks to Jonathan for his patience.
