I think that ‘tellers’ enjoy telling, and assume that other people will naturally do what they they enjoy, too — so, by this logic, the ‘asker’/‘listener’, by asking questions to prompt the telling, is demonstrating a genuine interest, and, the teller presumes, enjoying themselves. If they weren’t enjoying the telling, they would, the teller thinks, not ask questions, but would ‘tell’ themselves, because why would you ask to be told if you didn’t enjoy being told? .
They’re operating according to different rules, whereby everyone does what they prefer, and you just wouldn’t do what you didn't like ie, you wouldn’t ask questions unless you genuinely wanted to be told the answers.
They don’t recognise a social protocol by which there’s an implicit understanding that one person makes polite enquiries in the expectation of being asked them in turn.
(This is my father, by the way. I don’t think he has ever asked me a question about my life in my 52 years. If I want him to know something I just tell him, unprompted. In return he will deliver monologues on a change to his pension, or how, having decided he would not be returning to London after I left, he managed to have the balance on his Oyster card refunded, after several long international phone calls with probably baffled TfL staff…😀)
