You want to know how I can tell? In Venice a man assumed I was Italian and in Naples a Neapolitan woman asked me for directions on the subway! Me!
This may not seem like much to you, but for years every time I have spoken Italian in a restaurant or store in Florence, the response is always in English. So disheartening after all the work I’ve put in learning to speak Italian and blend in fashion wise.
And, I knew the answer for the woman on the Neapolitan subway!
I have arrived! Finally!
