Can people call English their native language if they've learnt it for about 15 years already? Thank you very much for those answers. I know that, but i just wanted to know, whether you can call any language you second mother tongue or something like that, not official, but because you feel so? So it's hard to understand it, and i'm not pretending to call English my second mother tongue, but i really want to talk about it with someone else))))) How you'll understand me. And once again thank you for all your answers))))))) P.S. If someone wants to talk about English and how she/he likes it, you're mostly welcome))))
