"Mind your language" - do you remember that funny British sitcom from the 70s, about a class of foreigners learning English?
Yes, it's interesting how you can see languages from different perspectives, and still learn new things yourself about your own language.
I've definitely noticed the same thing about losing some of your native language - since I have not lived in Sweden for over 10 years (and despite working in Swedish here a few years, having Swedish friends and speaking Swedish here at home with my son), I often find myself looking for words and expressions when I am back there to visit. I think it has less to do with the time in life that you learn a new language, and more to do with how many languages you are currently using at the same time on a daily basis.
And a few times I have also begun using "the wrong" language with people in different situations. You do feel a right eedjot then, don't you?
Where I work people speak many languages, and we have two main working languages, so whenever you speak to someone, the first thing you establish is what language to speak! Another fascinating phenomenon I've seen here and nowhere else, is two people talking to each other in one language each; which is quite clever actually - they talk in the language they are most comfortable expressing themselves in (English or French), and they both very well understand the replies in the other language!
Another kind of weird thing I've found is that, since I use several languages - but mainly English, I think to myself in English. And even dream mostly in English! Hm.
Hm, Massachussetts - can't say I've been there; an interesting place? I lived 2 years in San Francisco - loved the atmosphere, the city, and the SUNSHINÈ!!!
