Hi 4ndy
The New History Generator definitely can help, but it's not the only way and using it could be time consuming as you go through an unhappy childhood. Unfortutately, that's something too common. Fathers tend to be afraid of giving physical love or developing a close relationship with their children mostly afraid of being accused of sexual abuse (I have this personal theory that mainly says that a generation of underloved children is fertile soil for developing criminals, wonder why criminality raises year after year apparently without control?).
Actually, I find Alex suggestion on the Relationships tape interesting. I have 20 paraliminals and I most of the time overlook some of them. I'd give Relationships tape a try. In fact, I'll review it and see if I can apply it to my own situation. It could work faster than New History Generator.
