It is the rule of convents that members do not travel alone. The presence of a companion is a protection, and at the same time preserves the good Sisters from the scandal evil-minded people would be so ready to propagate if they were seen travelling and entering houses alone. I wonder whether you would always have the charity to believe that it was the home of her relatives, should you see a young Nun entering or emerging from a house by herself?
