i think sometimes when a person face a painful situation his mind will find an "escape" like Mrs Yang here are blaming Xiu Mei to lessen her guilt she knew that but if she didn't put the blame on her she will blame herself for not protecting her daughter or being late to rescue her and that will made her to never able to stand the situation so she did to deceive herself
Why is Xue always thinking of that? Doesn't she have a family who cares for her and brought her up?she gas to live for them n for her friend. Her friend must be disgusted as to how she cries n makes herself I'll at her grave. She should be telling her friend about all she did and how she would have liked her friend to have seen n done all these too
