Moved around a lot when I was a child, between multiple areas in two very large countries. It wasn’t just the dialects that changed, but also the language itself. I’ve lived in three different language regions. As a result, I’m now trilingual and can speak multiple dialects in two of those languages.
But my accent doesn’t fit any of those languages or dialects, it’s a weird blend of them all and it makes it seem like I’m not a native speaker of any of those languages.
