Culture and language influence our identity and communication behavior. In romantic relationships, this leads to particular challenges in interactions when partners come from different cultures. However, such a constellation also offers exciting opportunities to explore both one's own and the other culture. How are the partner's traits perceived in contrast to one's own culture in bicultural relationships? Are there even cultural differences? If so, what are they? The basis for this investigation consists of 32 interviews with individuals from 20 countries on topics such as cultural identity, politeness, family concepts, gender roles, dealing with foreignness, taboos, stereotypes, and much more. A comprehensive synopsis of cultural specifics, which the author has extracted from the accompanying corpus, can be viewed on the publisher's website.
