The way people RP conversations is incredibly unrealistic.
You have people monologuing without room for others to interrupt or prompt with a few questions, nor telegraph their disgust/disinterest which would normally make the person talking pause and start to feel awkward.
And, you have the thing where someone is trying to be as inclusive as possible, so their pose includes a sentence of dialogue directed at every single person in the room, addressing every topic that's been raised, leaving nothing out, lest others feel ignored.
I have a regular RP partner I annoy on these fronts because he'll consistently drop a paragraph of text with 5 different talking points and I just have my character react to the very last thing he said. Usually the quip portion instead of the actually important stuff. And then he gets frustrated I didn't comment on the actual plan or whatever, to which either my character replies, 'sorry, that was a lot to take in' or I tell him OOC that he needs to give my character room to respond if he actually expects me to.
These are two people talking! It's not an email exchange! There are no paragraphs and subheaders in a normal conversation.
