Greetings in Italy are typically warm and involve a handshake. It's common to greet people with a friendly "Ciao" or "Buongiorno" (good morning) during the day. In the evening or when meeting someone for the first time, "Buonasera" (good evening) is more appropriate. Italians value politeness, so don't forget to use "Grazie" (thank you) and "Per favore" (please) when appropriate.
