"We all to some extent meet again and again the same people and certainly in some cases form a kind of family of two or three or more persons who come together life after life until all passionate relations are exhausted, the child of one life the husband, wife, brother, sister of the next. Sometimes, however, a single relationship will repeat itself, turning its revolving wheel again and again."
