I think your german ist very well and I understand all what you say.
So don't be disheartened you are good.
;)
In Germany we seldom hear about Tunisia and even less about the politics.
But I have heared about the new constitution in your country.
Also I know that Tunisia is the first Arab country to represent the equality of man and woman, but I don't now what that means for your everyday life.
You live in a younge country and changes need time, so I think.
Nevertheless your country is so beautyful and unique.
Your nature is amazing and you have a awesome culture.
(it's my opinion, course I see the pictures about Djerba on google ^_^") You have luck to live there.
But is the politics the reason that you will leaving your country and come to Germany?
