no it isnt, for example,I do not speak with my parents,rough child hood,dad is a drug addict, I often remember boiling water so I can have a hot bath because drugs were more important than his kids. eventually it spiralled into him stealing from family, and my mother stood by him condoning it.
they havent met my kid never will, even though last week my mother contacted me to tell me she has advanced colon cancer.
so no not everything is forgivable,and her illness doesnt erase the pain the two of them have caused me.
