@poojakumar Have you ever heard the theory that Men are Bastards? Well... Not all men our! I believe that the cause is more neurological...
Girls come around to parenthood through a set of menstrual pains and this allows them inspiring focus on their future bloodline. They are Queens. They have eggs.
Boys come around to parenthood through a set of sexual pleasures and this allows them escapism from all of the realities involved in family life. They are drones. They do not have eggs.
