Italians in small town or village who are talking to people in the same village will usually use the local dialect of Italian such a Florentine, Milanese, Roman, Neapolitan, Sicilian, etc. When Italians greet other Italians from elsewhere or if they live in a large city, they use proper Italian. If an Italian is conversing with a foreigner, he may use English or French instead of Italian.
