Gift giving is a major part of relationships in many cultures. I was in Chicago when I studied anthropology. By means of detailed ethnographies, I visited fascinating peoples all over the world. I went to Central America and studied the advanced cultures of the Mayans and the Aztecs. I crossed the Pacific and studied the tribal peoples of Melanesia and Polynesia. I studied the Eskimos of the northern tundra and the aboriginal Ainus of Japan. I examined the cultural patterns surrounding love and marriage and found that in every culture I studied gift-giving was a part of the love-marriage process.
