I hate my grandfather for talking about my dead sister
Why did your grandfather do that?
I don't know. I didn't like it at all, and he knew I despised his words.
He shouldn't have talked badly about your sister. It was good that you stood up for her.
He is an annoying asshole. He always did it little by little.
It's wrong of your grandfather to do that when he knew it made you feel bad. Family members should be kind and supportive to each other.
