Berlin is full of life lessons. It's a city with such a vast history...albeit, it's mostly ugly history but Berlin is and has been one of the most famous cities in the world. Most of the history is depressing but to be in such a place, and to see the German people try to rebuild themselves after another ugly mark in their history was so incredible. This was probably the city in which I took the least pictures because I was trying to soak it all in and really think about the history through which I was walking. Whether it was passing through Checkpoint Charlie, looking at the beautiful graffiti on a wall that used to separate countless lives, or standing over the bunker in which Hitler killed himself, you really start to understand how much adversity that this city has survived. I admit that most of the tours were sad but I think it was so important to see and feel the history of this place in person so you can fully comprehend how vital it is to never let anything like the Holocaust, Cold War, oppression, etc. happen again. Thanks Berlin for that lesson that we all need as global citizens!
