Reasons i feel like i'm in berlin right now:

I spent yesterday evening hanging out in the squatted entertainment area metelkova, which would not be in the slightest bit out of place in berlin.
I just ate felafel, which is, of course, one of my favourite things about berlin. I even sat on a river bank to eat it, which is one of my berlin traditions.
It's warm and sunny, while still being jumper weather which is how i mostly remember berlin, as i've almost always been there in spring early summer.
While wandering around today i occasionally smelt coal burning, which i first learnt to identify in berlin.
The sharehouse flat i'm staying in reminds me of any number of places i have stayed in germany, both in architecture and atmosphere.
The currency is the euro.
There are interesting people wandering about interesting funky areas of town.
I can reasonable expect anyone i encounter to speak english- even those over 30.
Overall, Ljubljana is a cool and funky little town, and i have a feeling i will be back again before long!
