In a sense, sure I guess my brain almost always knows whether I wanted a question or not - after all, native English speakers have no problem asking questions. However, it's hard to get used to it, when I've never done it before.

It's like a habit. Imagine you make coffee every morning - after a while it becomes second nature and you don't even think about what you're doing, you just get up and mindlessly start the coffee grinder. Once in a while your girlfriend visits, and she wants milk in the coffee, no problem, I'll pour some milk on her cup at the end.

And one day you have a different girlfriend, and she doesn't like coffee at all, so when she's visiting you have to make tea! So you just get up, start grinding the coffee, and half a minute later, "Oh damn, not again!" Even though making coffee and making tea take about the same effort, it just throws a wrench in your morning routine until you get used to it, which make take a long time.

> If not, there are plenty of ways to bail out of a statement midway through a sentence.

Sure you can also do it in English, but you can't do it as gloriously as in Korean, where you can start the same sentence and end up with:

한국어는 영어보다 더 효율적입니다. Korean is more efficient than English.

한국어는 영어보다 더 효율적...(read the room, oh no, bail out)...이라는 헛소리를 하는 사람이 다 있더라고요 하하하! => I found an idiot saying Korean is more efficient than English, ha ha!
