Have you ever disowned or completely cut off contact with a family member? What about an immediate family member (mother, father, brother, sister)? And I mean COMPLETELY cut off contact, not "I don't talk to them but I will still send them holiday cards, etc". How did you do it? Why did you do it? If you haven't, would you? Do you think there is any justifiable reason to cut off contact with a parent, or do you think someone who does that is ingrateful?
