Conversations in the real world are nothing like this, filled with awkward pauses and words like "um" and "uh" and "derrr." People mishear things all the time, or misunderstand them entirely. Awful jokes are commonplace, and nearly everything uttered is completely banal. Listen to a conversation someone else is having on a bus sometime. The most trite, straightforward observations are repeated as if they're great pieces of wisdom, and everything is dramatically oversimplified. I don't know if I've ever heard anyone say something about politics that wasn't completely wrong, and I'm constantly having to interject and correct them.
"Sorry to interrupt, but ACTUALLY, a single-payer health care system has a number of advantag-"
The weird thing about this is that the same must apply to conversations you yourself are in, even though you don't notice it. There's something about being invested in a conversation, trying to come up with your own jokes and clever insights, that must distract you from how trite everything you're saying is, and you're generous enough with your friends to overlook the same missteps when they make them. Or you see but choose to ignore them, like laughing at your boss's jokes for the sake of professionalism.
