I used to be fairly good at speaking Spanish, but I've lost a lot of the ability to converse; I can understand most of what's said, but I lack the ability to reply.
I'm in the process of teaching myself Cyrillic now; I'd like to think that I'm making okay progress. I'm at the point where I believe that I can pronounce words correctly, but I don't always recognize what the words mean until I look it up.
