Olya, that is incredible. (that you never speak in English)
If I pass through your area for some reason or another I'd like to SPEAK with you.
Perhaps then I'll be ready to open my mouth and say something in Russia!
I've been through the challenge of learning English, and I'm not pretty much at a level where English people aren't really sure if I'm English or not.
But it took a lot of time and effort to get to that point. Plus I had the benefit of starting very early. Ten, I think. I watched TV in English with subtitles, and listened to a lot of English music. Later I travelled in countries were English was spoken. STILL, despite all these advantages English was hard for me.
The trouble if you are from a small country, like I am, you have no choice regarding English if you want a professional career. It's a requirement for university and most good jobs.
The situation with your English skills is pretty fascinating.
