What is the relationship like between Grandmother and Grandfather?Quote from the text to support.

Grandmother is her own person. She refuses to "obey" grandfather. This does not mean she does not love him, she just speaks her mind when she feels it is important to. Grandmother, the only one who disapproved of Father's new uniform, had said to her son, "I wonder if all the performances I made you give as a boy led you to this. Dressing up like a puppet on a string" (90). Grandfather had encouraged her to be quiet, but she had not obeyed.
