Kind of going through that right now. My father left home when I was 6 and we never had a good relationship even before that. He has cancer now and just went through surgery, and while I do feel for him, I don't feel what I suppose people expect me to feel as his daughter. I empathize with him just like I would with just about anyone else that was going through the same situation. My mother calls me cold but I don't understand why she expects me to react to this as if he was father of the year. His illness, though sad, doesn't automatically make me forgive the years of neglect. He still calls me out on any chance he gets, nothing I do is ever good enough and the only path good enough for me to follow is whatever he tells me is good. He doesn't exactly make things easier if he's not willing to admit his own faults.
