English is, of course, my second language, maybe that's why you didn't quite grasp what I was saying.
The burden is not in knowing another language, the burden is in making the "less useful" language your main one.
Your parents and all of the parents in the immigrant community you live in are very happy that English is now your main language which you acquired through school, friends, tv etc. Or maybe they put you in your-language-only schools, made sure you socialized with your-language-only friends and watched your-language-only media?
