Greetings
Man greeting Man - Men shake hands when greeting one another, while maintaining steady eye contact. At a first meeting a handshake will suffice but it usually lasts slightly longer than the typical North American handshake. Hugging and backslapping are common greetings among Brazilian friends.
Man greeting Woman - If a woman wishes to shake hands with a man, she should extend her hand first. It is common for men and woman to exchange kisses on the cheek when first meeting in social situations. This is often accompanied with a touch on the arm and shoulder. Some Brazilians kiss one cheek, but most kiss two or three times (alternating cheeks).
Woman greeting Woman - Women generally kiss each other, starting with the left cheek and then switching to the right cheek. Some kiss one cheek, but most kiss two or three times (alternating cheeks).
