But yes, coming back is always a rough change. I remember, the first time I came back to Berlin after a few years, and my friend wanted to buy something. She was taking stuff from the shelves to look at it, which quite obviously upset the salesperson, who was following her and moving the items back into the right position. Finally, my friend had two items in her hands, trying to figure out what to buy, which prompted the sentence "Do you now want to buy something or just stare holes into the air?" I found it really touching to hear this true classic on my first visit to a store. This was Berlin as I knew it.
I had to laugh so hard. Which didn't help the situation, but I found it really funny at that point.
