Are quite different. Take own case. I have honor to be member of one of oldest line marriages in Luna—and, in my prejudiced opinion, best. You asked about divorce. Our family has never had one and would bet long odds never will. A line marriage increases in stability year after year, gains practice in art of getting along together, until notion of anybody leaving is unthinkable. Besides, takes unanimous decision of all wives to divorce a husband—could never happen. Senior wife would never let it get that far."
