Quick question a,
Have you ever been speaking English and suddenly thought... wait, why does my native accent just come back?
This actually happens to almost every intermediate and advanced English learner and there's a really fascinating reason why.
Your brain is literally working against you (and being very lazy!).
I just posted a new YouTube video explaining exactly why your native accent keeps creeping back in, even after years of practice, and what you can actually do to stop it.
It's a short one, but I think it'll make a lot of things click for you.
