There's a couple of people on family Zoom meetings who join us a lot. I've always found them a bit irritating but Zoom is making it worse. Zoom has a second of delay, so if someone interrupts then nobody can hear anyone. I actually had to tell them very firmly the other day to STOP TALKING but it never lasts.
I know it's a new thing for a lot of us but I've learned that you really do have to behave slightly differently with online chats, precisely because of the delay. There really does need to be only one person speaking at a time, otherwise there's no point. Most of the rest of us have passed this learning curve now but this particular couple haven't and they're really pissing me off.
People who constantly interrupt you mid-sentence are bad enough usually, but this is making things worse. They also do the thing where they ask you a question and then start talking over you while you're trying to answer.
I would appreciate any advice you might have about how to sort this out. They just won't listen.
