Except when neither of the divorced parents has any money, and you get zero birthdays and zero Xmas, but a whole lot of yelling from both sides about how lucky you are and how "I don't need to get you anything, that bitch/asshole of a mother/father will get something for you."

It's what my wife went through. But she is doing a great job as a mom and a wife because she made up her mind to be different than her parents. She also went from a size 20 to a size 8 over the past several years of constant effort but that's another story.
