Our producer Wojciech has a theory that Central and Eastern Europe, in their broadest sense, share a common trait - they do not tolerate emptiness. Any deficit or shortage is promptly filled by individuals who have come to realize that they cannot always depend on their states to provide essential services. This is precisely the theme of our interview this week, with Ilir Gashi, who shares his story of getting involved in an unofficial courier system between Kosovo and Serbia when the state postal office ceased its deliveries. Against the backdrop of recent tensions between these countries flaring up once again, it provides a poignant glimpse into the daily life on the border of these nations.

Last week, dozens of NATO peacekeepers were injured after violent protests broke out in northern Kosovo. What is going on, and why do Kosovo's problems seem so hard to fix? This week we dig into the deeper context behind the unrest with political analyst Agon Maliqi. We're also talking about why much of Europe is antsy about who's going to be steering the EU next year, and a bizarre dispute in the art world.
