I think it's about a woman who is haunted by her past. The past, though bad (her husband/boyfriend killed her lover, both are dead) provides some comfort to her. She is now telling her son not to make the same mistakes that she did, but she knows that because he is her son, he'll make the same mistakes. He won't be able to listen to her words, because he's seen her actions and will repeat those instead.
