Intercultural connections of all kinds (race, ethnicity, nationality, religion) happen at two levels – in public, and in private. Most research focuses on the former, but there is much to be gained by studying the latter. People who have intercultural friends have to discuss and face their differences, and find a way to manage them, and this is even more true for intercultural couples and families, who often are making a longer term commitment to an Other. There is a growing literature addressing the topic.
