Mixed couples, as one of the determinants of breaking distance of historical, cultural, psychological and social nature, trespass the fundamental principles that separate a group from the “Other”. This otherness makes the couples of this type evoke social attitudes of integration or isolation. A relationship is seen as mixed when the difference between the partners is considered significant by them or by the local community. When one speaks about everyday life of Polish-German couples living at the new north-western border of Poland after 1945, an important factor in their formation, i.e. the historical events of World War II and the sense of temporariness until the western Polish border was settled in 1950, cannot be overlooked. After 1945 mixed couples were an important part of the image of the border area, also integrating the Polish community with the remaining Germans. They formed the part of the first generation of such couples, which encompasses the years 1945–1971, the opening of the border with East Germany in 1972 gave rise to the second generation, which lasted until 1989, while accession of Poland to the European Union marks the end of the third generation. In our text we shall only focus on three aspects of everyday life, i.e. the formation of the German-Polish relationships, negative contacts with the surrounding environment and problems with authorities.
