Telling example.
If the DM (or other player) is in a mindset of evaluating or assessing the validity of the roleplay, just as the teacher is grading exams or an academic is reviewing an article, then...yeah. That's going to happen.
But is that the job of the other people at the table?
I wasn't going for the parallel in jobs, I was going for the idea that sometimes something breaks you out of what you're trying to do.
I could have gone with watching movies and noticing shots that zoom onto logos and finding yourself wondering about product placements. If you don't usually notice the brands that show up in movies and don't bother to usually check product placements -- but once every dozen movies there's a stop motion pause onto the hood ornament, and when you check it was a product placement -- is that more a viewer thing or a movie maker thing? Or maybe it's reading historical fiction and having bits of modern slang or current news references show up.
