Step-by-step explanation:
The greeting between male friends in Argentina typically involves a light kiss on the cheek. This form of greeting can be seen as a cultural norm in many Latin American countries. It is important to note that cultural values vary greatly around the world regarding physical displays of affection among friends. In the United States, for example, it is more common for male friends to greet each other with a handshake or a hug, and a kiss on the cheek might indicate romantic involvement. However, such gestures can have different connotations in various cultures. In some parts of Africa and the Middle East, men holding hands is a normative sign of friendship, while in parts of Europe, such as Italy, a kiss on the cheek is a standard greeting among friends regardless of gender.
