I don't mind repeating myself in saying that I am in love with that city - always was and always will be - eventhough or especially since I have left it 10 years ago. Everytime I go back to Berlin it's a bit like a time trip into the past and the future.
Gladly I can still discover so many things that remind of my first big chunk of life there - although many of them are disappearing rapidly or have already done so. So when I get back - I often get a bit sentimental - especially when it's Christmas and the city is dark and covered in snow.
