Yes, listening to people yammer on about subjects I have zero interest in can be irritating and tedious. That said, if I’ve let someone yammer on at me for ages about something, I think I am partly responsible for the situation, because I’ve not done anything to stop them from dominating the conversation. No one can yammer on if someone isn’t letting them yammer on to them, I guess?
I don’t find it triggering - for me it’s just a disconnect in that the topic of conversation at that time is interesting to them and not to me. If someone is talking at me rather than to me - they’re just broadcasting at me, they’re not interested in anything I might say, they’re not making it easy for me to get a word in, they’re not listening when I do speak etc - that’s more of an issue for me as it would feel like they’re not valuing my input, they’re not interested in hearing me etc. I’m not sure that’s what you’re talking about though - I think it’s more that you’re saying you get annoyed when people talk to you at length about things you’re not interested in? Is that right?
We’re not all interested in the same things, of course, so I’m sure there are also times when I‘ve talked to people about something and I’ve been on a roll with it and they maybe haven’t been that interested. I think I’m pretty good at reading people and noticing if people are glazing over or switching off or looking like they want to wrap the conversation up etc. But if people - especially if I don’t know them very well - are doing a good job of feigning interest, it can be harder to pick up on that.
Change the topic of conversation or wrap up the conversation...can easily do either of those things without being rude or mean. I personally wouldn’t ever say something as blunt as “can we change the subject because I’m not interested in this?” For me, that feels uneccessarily blunt and rude (just my personal view) I. These sorts of situations, I would change the conversation without specifically saying so...just steer the chat to something else. And, if they still talk at me and don’t “allow” me to talk about something else, I’d wrap the conversation up because it’s not really a two way thing and I want my intereactions with people to be a two way thing.
