I speak fluent Spanish, and basic Mandarin Chinese.
I can (and have) worked in an exclusively Spanish atmosphere, and though they can tell I'm not a native speaker, people typically don't slow down sentences or use simpler words simply because I'm American. My accent is good, and I've been told it sounds like I'm the child of a Spaniard, which I'll take as a compliment with my super gringo parents.
With Chinese, I can give directions, order in a restaurant, negotiate/bargain, explain why I know Chinese (studied in Shanghai for 4 months), discuss places I've lived/traveled, and that's about it! It's sad how much I've lost - I would love to get more of what I had learned back and learn more.
I really want my husband to get stationed overseas in Germany or Japan so I can learn another language. I really wish South Korea was an accompanied post (meaning spouses could go) because that would have been my first choice. I'd love if DH could be a legal attache to an embassy one day in Europe or Asia - I just love to travel, I'm not super picky!
