What is the probable relationship between the two speakers?

Jim: Oh, Rod! Um, welcome back!
Rod: Hi Jim. My goodness! What on earth happened to the flat?
Jim: Er, I had a party with a few friends.
Rod: A few! It looks like a bomb fell on in.
Jim: Look. I’m really sorry. I wasn’t expecting you back so soon. I was going to tide every-thing up before you got back.
Rod: Hmm, hey, the leg on this table is broken.
Jim: Um, yes. I think someone fell over it. I’ll fix it. Don’t worry.
Rod: These are my records, aren’t they? This one’s scratched.
Jim: Is it? Well I’ll replace it, of course.
Rod: I’ve only just bought it.
Jim: Yes. I feel really bad about all this. You know what it’s like, Rod. Everyone was having fun and things just got, um, a bit out of head.
Rod: Some of our glasses are broken, too. Look.
Jim: Oh, I’ll buy some new ones. Um, I’m afraid the record player doesn’t work, but I’ll take it to the shop this afternoon.
Rod: Have you seen all this rubbish on the floor? Empty cans, bottles, food, serviettes, cigarette ends...
Jim: Yes, I was just about to clear it up. I should have been more careful.
Rod: What a disaster! What about these stains on the sofa and the cigarette burns on the carpet?
Jim: Um, I’ll clean the sofa immediately and the cigarette bums, I’ll... well...
