Now that I live abroad, I wonder if I'm slowly losing that "body language", and making myself harder to understand to other Italian speakers, entering some uncanny valley where I sound fluent, but something's missing. As a trilingual person, this is certainly would not be the first time. (The first language I've learned was French, I have perfect pronunciation but I've never practiced it and it became very rusty over the years, so it's now in that uncanny limbo and I actively avoid speaking it)
