They think they already understood.

I’ve had to have several conversations with my wife about her not using a bad mental autofill.

So much of the time (especially with important conversations), she’s already decided what I’m saying within the first few words (of an entire conversation) and then the conversation gets way too long because it is very clear she’s not getting what I’m saying because she’s locked into her autofill. She’s gotten better over time, but man is it frustrating.

Especially when they drag their point out for dramatic effect but the point was so glaringly obvious that it comes off as smug on top of the tonguebiting you have to do to not just torpedo their pathetic attempt at tension-building.
