The connection between father and daughter. The father is the daughter's first love through her years. A father should bestow good sound qualities and values to keep her heart strong.
Taking her out on dates, buying her flowers at Valentine's or just because..
Dad should show her how to change a car tire, or how to detail her car inside. Also teach her to wash the outside.
Teaching your princess how to be somewhat self-sufficient.
You will make her strong, and showing her that she is a powerful woman that can survive in a cold cruel world, and not fall subject to just anything, she can stand on her own two feet.
That is the greatest gift you can give a girl.
