It depends what kind of relationship you had with the parent(s). I'll give you an example: I've not seen my mother in half a decade, I've barely seen her in twelve years. Perhaps that's for the best, after all, she did just leave my father and I over twenty years ago to pursue a man twenty years younger than her from the other side of the world that she met in a psychic chatroom. When I have spoken to her, as recently as last Christmas, we only argue. I've tried extremely hard.
