sadness of happiest moment

In our tradition one day girl has to be say bye forever to her family to join her husband family . so after wedding there is ritual called vidai.here I clicked the picture of my sister hugging father ,weeping . it's very different moment on one side everyone is happy due to marriage on the other side everyone is sad because girl has to leave father.s house permanently . so I clicked this a moment of love and sadness and intense bonding between a father and his daughter .
