I tasted the language learning bug around 4 years ago when I trialed Spanish on Rocket Languages. I never bought a subscription, I was always gambling my money away at the casino but that's another story altogether.
I found it quite interesting and tried to impress the lads at work with conversing (at a pretty simple level) with an El Salvadorian fella that was fairly new to the English language. I tried to make him fill a bit more at home as well and communicating with him was great, even though I would stuff up a fair bit which was funny, but he sure did appreciate it as well. I don't know why I didn't continue with my Spanish. It was definitely easier than German. I think my gambling got in the way a bit ( I have since stayed away from my ghastly addictive disease)
Now, the reason I decided to learn German? Well, I have got to know a few German native speakers who left Germany quite some time ago and are quite fluent in English. They are Jehovah's Witnesses and I see them regularly at the meetings. I don't talk to them that often but when I do I would like to converse with them in their native language so I decided to give German a go.
I do find German quite interesting and quite hard sometimes but I would love to have it as a skill and not to mention impress people as well.
It's interesting that when I attempt to talk to ones from the Bavarian area of Germany, they can understand me quite well but when I talk to the much older Austrian couple they struggle to understand me and correct me quite a bit, with good intentions though!
I have tried learning German using Italki (skype) using a variety of teachers and community tutors but I seem to struggle with the listening part. I do ask them to slow down and most of the time they do but I still need to work on it quite a bit. It can be quite frustrating at times on skype but I believe if you can get the right teacher for you it can work out quite well. Of course, the money side can be an issue as well. Our dollar in Australia has been quite weak for a few years now and if it was up around par US I would be using Italki more often
BTW, it must have been a real experience teaching English in Germany. How did you go with communicating in German? Did it go down alright? Did they understand you? What were your biggest challenges with communicating?
