1.Almost all males of the human species ADORE their mothers and dote on their daughters. In the same breath most often look down upon the rest of the female gender some even going to the extreme of abusing them, their wives included!
2. Traditionally, men considered their daughters as less than valueless, and yet they comfortably transformed them into cash-cows, levying hefty dowry fees for the privilege of marrying them. In fact, men who didn't have daughters rarely had the luxury of marrying many wives as boys couldn't be "sold" to provide the dowry for the same.
