I've read too many stories about Naples before I was there that I have be careful while I'm there. I was very paranoia when I arrived there at the first day that people on the street kept staring at me. But the next day, I've found that, in fact, local people are very friendly, they smiled at me all the time especially middle age people. I often asked for the direction & the bus info from many people & they were really happy to help me even we couldn't communicate in the same language. Some of them just walked with me to the place that I wanted to go. We had the best & very cheap pizza there, the pizza man was very friendly too.
