It occurred to me last night that on the whole, probably around 30-40% of people I've met do this. Most of my extended family when I was growing up, most of my neighbours, some colleagues, people I've become friendly with on courses, people at a class I go to, people I've met at parties, people I've met at meetup groups and so on.
My ex would do it and I ended up afraid to ask him a question for fear of triggering a 30 minute ramble or retelling of a story. I had to ask him to please get to the point for my sanity.
Recently I booked an engineer to look at something in my flat, and we got chit chatting because part of his job turned out to indirectly involve an area I work in and did research in. He went off on a long-winded monologue about it, occasionally asking me a question but then interrupting me about 5 seconds into my answer to talk for another 10 minutes. He was a nice bloke and what he was saying was interesting to me, but I found myself wishing I'd never said anything.
I've started to chit chat with a nice woman at an evening class I attend, but she's beginning to monologue and ramble from one random thing to the next. I feel held hostage when I just want to get home so I need to start making a swifter exit.
I don't know if people just don't realise they're doing it. It feels odd to me because I'm always very conscious of how much I'm talking and whether the other person is interested or not, but maybe I'm hyper aware of it because of my mum.
I met up with someone I'm getting to know as a friend last week. We had proper two way conversations where we asked each other questions and actually listened to the answers. It was lovely, and such a relief.
