Like "Chees" I'm also from Bulgaria. Currently I study and Germany and the only thing I miss is the great nature because I'm a mountain biker and here in Berlin I can't do sh*t with my DH bike) What I do NOT miss:
-People behavior in Bulgaria.
-All sad faces in the subway when I go back from school.
-The so called bulgarian "villagers" not for the place they come but for attitude they possess.They mainly are uneducated egoists that care only for trivial things like what car do they drive how expensive their clothes look and what people talk about them.
-All of my bulgarian so called "friends" smoke, do drugs, listen to the awful music called "chalga", everything they say ends with a swearing word. They don't think about their future ... the only think in their mind is fu***ng minors, going to bulgarian chalga clubs https://youtu.be/KafdPmeLQAU?t=1m12s
earn money selling drugs etc.
- gypsy problem
From my point of view Bulgaria is a great place to live when you have established your income sources, buy a big house away from the big city -> live like a king. ( I was born in Sofia / the capital of Bulgaria / maybe that's the reason why I think like this. Mostly of the people who live in bulgarian provinces, decide to move to Sofia seeking for a better life/job etc.
