It is generally believed that there is a special chemistry between father-daughter duo like the mother-son bond. The man who is her everything from childhood is her father and her childhood had been revolving around him. In return, a father has special affinity towards his daughter, as she has to be so delicately handled and taken care of than a son.
Some fathers influence, inspire, pamper, take care and love their daughter so much so, that no other man in her life could catch up to that even by half its extent. She is so 'badly' loved by the father that no one else in this world, in the present and future, could love and care for her as much as he does. Thus, he sets a a standard so high that no one else would surpass.
