Mom and grandma have always had problems. When I came back from school today, I saw my mother with a straight face and my grandmother with red eyes.

It seems that the contradiction between your mother and your grandmother is not a day or two. Say something nice in the middle, and do something more at ordinary times. Tell grandma and mom more about her, and tell grandma and mom more about her. As you said, you can tell your mother that grandma is old and cook for us. Grandma doesn't often copy pickles. This time she just changed her appetite. Is it necessary to quarrel with her? You can say to grandma, grandma, I know you are old, and sometimes your hands and feet are not flexible. Pay attention to salt when cooking in the future. Mom is busy at work today, a little tired and in a bad mood. Mom said don't take it personally.
