I believe that some of this is differences in communication style. I like written communication because I don't process verbal communication as well. But I've also had plenty of colleagues who are more comfortable with verbal communication, and may not process prose as well. Many of them seemed hesitant to believe they'd fully understood something until they'd had a chance to talk through it to confirm. And, yes, needed verbal prompting in the same way that I tend to need written prompting.
The most functional workplaces understand and respect these differences and make room for everyone's communication style.
I am sympathetic to the "different communication style" line of reasoning, but I don't really buy it in the example I used / people I work with at present.
As far as I'm concerned, responding to some well-prepared prose with "lets discuss this", is just a non-response, and a refusal to engage. If one wanted to have a useful discussion, but preferred something verbal, actually picking up the phone, or responding with something like "I'm curuous about X/Y/Z. Let's discuss this at 2pm, I'll send you an invitation", or "please find some time in my calendar for us to look at this."
That would keep the matter progressing, and provide the opportunity to prepare for a useful discussion. "lets discuss this" is just saying "I need you to spoon-feed this to me, but I'm not going to make arrangements for that, so you'll need to figure out how to deal with that.".
Yeah that's true to an extent. I've also had many occasions where someone asks for an update on x and I respond with a two line email asking a yes/no question and the person just says "let's hop on a quick call" etc. That's so frustrating because they're turning 30 seconds into 30 minutes.
Not the person you're responding to but just needed to vent that. It's been happening a lot lately in my world
