I went to Greece a few years ago and a couple things stuck out that I hadnt seen in many other European cities. The first was an incredible amount of heroin users. I must have seen about 40 in Athens near my Hotel in the Plaka district.. just nodding out on benches. The second thing was how friendly everyone was, but how the older generation was really pissed off at the younger generation at how little they wanted to work. It was a major running theme wherever I went.
I loved so many things about Greece and its probably my favorite place I've ever visited, but its really fucked.
