Visiting a croatian island in the Adriatic see

I'm a really respectful, easy going and open person who had discovered that there is no better way to visit a new country than getting in touch with real local people and their routines and perspectives. Of course, maybe it could be interesting to take a picture on the most well-known sightseeing spot of the city, but getting to know a country is much more than that and towards sharing an experience with locals, in my humble opinion, is the most reliable way to appreciate a culture.
