"By what could such a situation be precluded?
By decease (change of state): by departure (change of place).
The latter, by the line of least resistance.
What considerations rendered departure not entirely undesirable?
Constant cohabitation impeding mutual toleration of personal defects. The habit of independent purchase increasingly cultivated. The necessity to counteract by impermanent sojourn the permanence of arrest." (U17.1954)
