One language, different ways of speaking.

I've been for 5 days in Napoli, an italian city. A south-Italy city. Also known as "Naples" for the world.
An old italian saying says: "you see Napoli, and then you die". Well, almost true. The view is amazing. One of the best thing i've seen in my whole life until now. No horizon line between sea & sky. Just blue, just amazing. I won't stop myself on these stuff, because it might sound lame or "copied" but seriously, it was amazing.
The thing that most got me surprised, was all the love Napolitans have for their city. You can do whatever you want, but don't touch their city, their places & their football team. At first, it sounded like bragging to me. But once i was there, i understood they're just like that. Maybe bragging, but not with that intention.
I come from a very small city, and napoli was just so big at my eyes. Traffic, cars, lights, old places, new places.
I found myself creeped out on friday, when i first got in the city. I'm italian, but everything looked like i was in another country. Nothing wrong with the people or the places. Just the language. I didn't understand a dick. Literally. Sorry for being vulgar, but seriously. I was like: "hey what's that palace?" and my friends were like: "that palace is bhfbghbfhgby, you understand?" "yeaaahhh o.o". It was their dialect. Too different from the normal italian to be understood by me. Way too different. I was creeeeped out. I'm still in Napoli now, but i finally can understand it better . Had to learn some famous sentences. lol
One language, different ways to speak it. It was insane. And i got to learn something in Sicilian, the dialect of sicily. Mafia speaking! ;D
I have to leave tomorrow. It was fantastic, i loved it here. But yeah, i'll come back for sure.
I'm starting to realize italy is better than i used to think.
Is it positive?
