I USED to speak French fairly well. I USED to speak Japanese. Now I only speak English. There really aren't any easy opportunities to put languages into practice around here--except Spanish, I guess... but I still haven't had any opportunities/contacts with Hispanics here either.
I learned in Japan that I couldn't fit more than one foreign language into my brain. I tried to help a trendy French lady who couldn't communicate with an elderly Japanese hostel manager, and never got a word out in French... just Japanese, no matter how hard I tried. I was aghast. The French gal finally blew smoke in my face and walked away.
