Lily finally opens her eyes to the possibility that female friendship doesn't have to be contracted (as in
laotong or sworn sisters) to exist and provide true intimacy and comfort. Snow Flower couldn't turn to any person with whom she had a contract (her husband and Lily) for comfort, and so turned to non-traditional and non-contractual relationships. This realization brings Lily down from her sense of superiority, as she finally recognizes that she herself broke the
laotong contract.
