I will attempt an objective comment here:
I tend to see things this way; If you can't change them, you accomplish nothing by letting them upset you. I know for a fact my family and hers are so indoctrinated, that in their minds, the way the treat us, is the way God wants them to treat us. So I accept it. I certainly don't understand or like it, but I know that I can't change it.
Lori sometimes you seem to take things personally, and that's understandable. But like Cult Classic said, there must be a different way to cope with the frustration.
