A handshake is the most common form of greeting in Angola, at gatherings each guest should shake hands individually. However, when meeting someone senior in status or age it is usual to bow slightly. Hierarchy is an important part of the culture of Angola, and titles and surnames are commonly used as a sign of respect.
Greetings are not rushed in Angola. You will be asked how you are, how your family are, and the person enquiring will be sincerely interested. It is not merely a formality as in many other cultures and it will be expected that the sentiment is reciprocated.
