Wisdom and Goodness are twin born, one heart
Must hold both sisters, never seen apart. [ Cowper ]

It is not virtuous women who are so ready to report suspicion of their sisters. [ Mme. de Krudener ]

Obscurity and Innocence, twin sisters, escape temptations which would pierce their gossamer armor, in contact with the world. [ Chamfort ]

We tell the ladies that good wives make good husbands; I believe it is a more certain position that good brothers make good sisters. [ Johnson ]

The bee is enclosed, and shines preserved, in a tear of the sisters of Phaeton, so that it seems enshrined in its own nectar. It has obtained a worthy reward for its great toils; we may suppose that the bee itself would have desired such a death. [ Martial ]

The love of a mother is never exhausted; it never changes, it never tires. A father may turn his back on his child, brothers and sisters may become inveterate enemies, husbands may desert their wives, wives their husbands; but a mother's love endures through all; in good repute, in bad repute, in the face of the world's condemnation, a mother still loves on, and still hopes that her child may turn from his evil ways, and repent; she still remembers the infant smiles that once filled her bosom with rapture, the merry laugh, the joyful shout of Iris childhood, the opening promise of his youth; and she can never be brought to think him all unworthy. [ W. Irving ]
