Yeah, some people see a conversation as a one-way street, a chance to just say everything that is in their head, like they're thinking out loud in a stream of consciousness. Such types love watching interviews on telly because of course in them it's just one person talking on and on, with the interviewer asking questions, for what might be an hour or so. At no point does the subject turn it around and ask the interviewer anything, it's not expected, and some people pick up on that kind of talk. It can be quite narcissistic, self-absorbed.
On the other hand, to be fair, TV dramas just don't do that kind of inconsequential small talk do they? Aside from the Royle Family, perhaps. Every conversation has to have a point to it, some progress or information, rather than a sense of getting emotionally closer through some kind of shared connection.
I had loads of flatmates like that. You start of all happy and taking an intersest, always being the first. They love it. After a while I'd be in a bit of an off mood and think, right, you make an effort now. And they just wouldn't get it. They'd get in a right strop - and then you'd be in a silent war with someone who never really speaks anyway, so you're going to lose that one.
Sometimes I'd get this with some who were only children - though I'd be happy to believe that's not the case of only kids generally. But I do wonder if some who grow up alone sort of are used to parents fawning over them and making them the centre of things. The idea that you must engage with another person on your level & make an effort may not occur to them.
That said, I'm doing the same thing now, aren't I? I do look back and wonder if by doing the whole Dale Carnegie trick of taking an interest in someone, it's not evident it should be reciprocated. It's not just about asking questions though, more coming up with your side of the bargain, a follow-on comment. 'Oh that happened to you? Well, a similar thing happened to me...'
I have found hypermanic people who talk too much suddenly get a strop after a while because you haven't said anything when in fact you can't get a word in edgeways.
