I find myself quite shocked at reading what Nastya below wrote. My name is Konstantin and I was born into a russian family in Smolensk and at the age of 14 i moved with my family to the United Kingdom. I live with my birth mother and step dad. I do, however, still regard myself as Russian as of course it is my first language. I speak it now poorer, especially written but it is still my native language and honestly speaking never will change, i still however find it easier for example to count in russian and to speak in russian rather than in english, however i am using english more. The weirdest thing for me is the amount of words one looses. For example, a friend may ask me how do you say such an such and I just can't remember that word.
I go to Smolensk normally at christmas and new year(not this year) in March and in summer for 2 months to stay with my grandmother and she sometimes says that some things i say just don't sound naturaly anymore to her, this for me is quite annoying because I question myself, why does it not sound natural, if i was a native. So i decided to study with the language a bit, but i find that i just can't, as everything i already know that are in courses, obviously I grew up there. So my only way to really study it now is by paying more attention. I understand completely, but I don't pay atttention to what I understand, therefore I am not reusing it. Does this make sense? =) haha

So i thought here i would leave a message. I am of course happy to make recordings etc if anybody would like, and help to best i can. Learning of learners of the russian language!
