Salvete omnes!
When I was 'deactivated' after the Gulf War, I stayed with my sister for a time. She ran a home-based business and had a lot of Spanish-speaking clients. Now, I don't know Spanish from a hole in the ground most days; and if Spanish knows me, it's not admitting it in public. So what happened when she wasn't home and I had to answer the phone? --I nattered at the customers in my piecework Latin, and they gabbed right back at me in Spanish, and we got understood. >({|:-)
(Mari's Latin isn't the best, but in face-to-face it's gotten a lot of airtime.)
In amicitia et fide,
