Do I really feel this anger enough to yell at my grandmother? It is killing me not to.
Are you kidding me, your grandmother is so old. She could feel so upset or even die from your yelling at her. Why do that?
She asks too many questions all the time, I also hate her for being so needy.
You should not yell at your grandmother. It it mean to do so and you could hurt her feelings.
Why not, I'll yell anyway.
Yelling is for abusive people, they don't know how to talk in a calm manner to get their point across. They think they are always right and it is the only way they get others to think that too. Be civil to her, and understand that elderly people all go through that just like you will one day.
