A greeting is a way of saying "Hello" to someone. People in different countries greet each other in different ways. Here are some.

World Greetings

Philippine	The everyday greeting for friends is a handshake for both men and women. Men sometimes pat each other on the back.
Japan	When people meet for the first time, they usually bow. In business, people also shake hands. In formal situations, people often exchange business cards. When you give a business card, give it with two hands. This is polite. Special note: In Japan, a smile can have different meanings. It usually means that the person is happy, or that the person thinks something is funny. But it can also mean that the person is embarrassed.
New Zealand	Usually, both men and women shake hands when they meet someone for the first time. Fun fact: If you see two people pressing their noses together, they are probably Maori. The Maori are the native people of New Zealand. This is their traditional greeting.
Brazil	Men often shake hands when they meet for the first time. When women meet, they kiss each other on the cheek. Women also kiss male friends to say hello. When you shake hands, look at the person in the eyes. This shows interest and friendliness.
