What are the key differences in appropriate physical greetings (e.g., kissing) in Northern versus Southern Italy?

Physical greetings, particularly cheek kissing, vary in frequency and formality between Northern and Southern Italy. In Northern Italy, cheek kissing as a greeting is less common, especially between acquaintances or in more formal settings. A handshake is generally considered more appropriate in initial encounters or professional situations. When cheek kissing does occur, it typically involves two kisses, starting with the right cheek. However, some regions might prefer only one kiss. In contrast, cheek kissing is more prevalent in Southern Italy, even among people who are not particularly close. It's a more common way to greet both men and women, although men might still opt for a handshake with other men, especially in formal contexts. Similar to the North, two kisses are typical. However, the specific customs can vary even within smaller regions, so observation is always helpful. Understanding these regional differences is important to avoid making anyone uncomfortable or appearing impolite.
