HOW SPANISH PEOPLE GREET EACH OTHER

In Spain, the greeting habit of kissing relatives and friends on both cheeks is very common. Men normally shake their each other's hands when it comes to meeting close friends, as well as meeting other people in formal situations. Among women, the most common way greeting habit is kissing each other on both cheeks. Teenagers normally greet each other in a similar way or, more informally, by clapping the back of their hands. Youngest children usually shake their hands, or if they are relatives, e.g cousins, they kiss each other as well.
The more common verbal expressions are ¡Hola! or and ¡Qué pasa!, especially among young people. In more formal situations, when there is a big age difference, they say: ‘Buenos días’, ‘buenas tardes’, or ‘buenas noches’, depending on the time of the day. Unlike in Britain or The United States, the expression ‘buenas noches’ is commonly used when greeting or saying goodbye as long as the encounter takes place at night.

Very good job!
