"Asking for advice"

Dear grandmother,

I've got a problem and I need your advice. Mom and I still having some kind of disagreement. Every time I try to help her, she always defy me on everything. For example, last night she was sitting on the chair and I was watching movie. Suddenly, we remembered that we have forgotten the time to make the dinner. We started to prepare the dinner stuff. I peeled some vegetables, cut the meat and cook the rise for dinner. But mom got angry to me because she wanted soup. But I told her, we have just ate the soup yesterday and today I want different dinner. But she never agreed with me and made it on her own. I didn't really like and I didn't eat my dinner. This is the simple example of our disagreements. I don't know how to become one minded person with mom. Grandma please, help me. What do you think I should do to make mom on my side.

Love,
your grandchild
