As has been said elsewhere here. We responsible men have a duty to improve our girls. There are basically two, but only two, elements to this: firstly, they need to be shown/told how to behave and how they shall be formed, and they need this over and over, patiently, consistently, and clearly. Secondly, they need to be told in a way they understand it. Some would need tender persuasion, some brutal force, but most would need a mix. This one is tilting towards clear disciplining, combined with brutal punishment if slow to submit and adapt. Hard work and sweet pleasure.
