Tongans in the South Pacific lower their heads to show respect. You can visit their homes, even uninvited, especially on Sundays when businesses are closed and transport does not operate, according to Tongan law.
Tongans usually take off their shoes when entering houses. Most meals are enjoyed on woven mats on the floor. Men sit cross-legged on the floor, while women fold their legs back. Guests are served first, and small children are seated separately so as not to disturb the elderly. Do not bring food to share at a meal. It is considered rude as it implies that the host has not prepared enough food.
Gifts commonly exchanged between hosts and guests include mats, flower necklaces, beads or shells, and small gifts for children. Finally, it is customary to make a small speech before leaving to thank your hosts.
