Languages really do catch my interest, for so long.
Indonesian is my mother tongue but I've learned English since I was young (approx. 10-11 years old). So it's been ages English has been my second language, but still I found out that I am not as good as native speakers (of course). I would rate my English fluency something between intermediate level to advance - but then, as long as I survive with my language capability (know how to order food, find direction, even in my case, doing a literature review) I know it's not a problem whether my degree of fluency is advance or not.
Just couple of years ago, I also interested in Deutsch (German) and Français (French).
I took a private lesson, and just when I was about to master (well, master my basic lesson- that's what I mean :) I had to leave to Europe for my master program.
But then I found out that my Deutsch was actually really crap in practice, because I couldn't understand what these Germans people were saying. My Français was a bit (slightly a bit) better cause I could understand a bit- at least I got the important point of conversation- but most of the times I kept using English instead of 'parlez Français' (when I was in French speaking area).
It's so lame... I think it's all just the matter of practice and confidence of making mistakes :-)
I'm sure if I settle longer in France or French speaking regions, I'd definitely enhance my Français competency :-)
I also learned a bit of phasa Thai when I was in Thailand (for short time), but every Thai people that I met told me that I had the right accent. So it was really encouraging :-)
Also a bit of Dutch when I was in Netherlands (I was there cumulatively for almost 5 months). I didn't really learn it the way I learned Deutsch or Français. My Dutch language lesson was basically because I hang around with friends and colleagues (and people around me in public spaces :-) who speak Dutch. But I came to conclusion that in Netherlands, almost all the people that I met could speak English very well, so I didn't have to learn Dutch at all :-)
Danish, even though I stayed in Denmark for more than 6 months- is something that I gave up to master. I know how to say basic things e.g. salutations, thanks, sorry, sale/discount, but that's all.
For me it's a bit frustrated to learn, for it pronunciation is tricky - and did not sound as beautiful as French or Italiano. Sorry Danes, but this is the fact from a foreigner.
Then I also love Itali. Mi amore Italia :-)
And Italiano is a very beautiful language, they also have a lot of meanings in sentences.
For example saying thanks in Italian is 'Grazie' (just like 'Merci' in Français) it has more meaning than just 'thanks' - it's more like 'grace' or 'mercy'. Showing more feelings of compassion and thankful. I just love it.
Not to mention the rhyme when people talked, or even argued about something.
And how they categorize feminine and masculine words/ nouns (similar like French), based on, what?
Anyway, this is the language I'd like to learn more in the future.
Sorry it took so long to come to the point, that International Sign Language is totally almost left out in my to-do-list.
I had this motivation to learn from few years back then, it keeps coming on strong nowadays.
Then I found out that I could actually learned it by myself (thanks to google). They put so many videos about it in webs. So I'm going there now.
We'll see how much I'm getting serious about this in the future.
