Glad you finally managed to get a bit of exercise. It must make a big difference to mood. I know it does with me and my situation is not nearly so hard as yours!
Deb you are always doing your best to pay attention to everyone here, I wouldn't worry about the rest. I often completely misunderstand things too. I think everyone has that about some things
"Today the warden summoned all the foreigners for a "friendly" talk. There are 19 of us, 9 of them Korean. There is an Indian with HIV who wasn't summoned. And 5000 locals."
What was the chat about? It sounds a bit intimidating.
If there is one thing I have learnt about learning a foreign language since moving here is that the people who like it, learn it, if you don't enjoy integrating, you also struggle to learn the language. It doesn't seem to have much to do with latent language abilities or intelligence. So I can quite imagine that you can pick up any language you want to quite easily, but as soon as you get out I don't think you will remember a word from this one and that will probably be a nice thing for you.
