It is often known (atleast among me and my friends) that when someone is damaged as a child mentally, they stay the same mental age throughout their life. Women are fragile, weak, mentally and physically. Maybe its cause women are weak that they get damaged as a young one easily, and they stay their mental age, which produces female behavior of being a parasite, like a child. Difference is, is a child is a parasite only because it has to, and its ok. But the female on the other hand is just a parasite.
