Who is Grandmother from My Life and what is their importance? My_Life_(novel) English & Literature Grandmother | My Life

Grandmother is a Christian Scientist. Wearing a washdress, she stands in the kitchen with her hands on her hips and states that she is waging war now as she watches a line of ants cross behind the sink faucets. At night, the narrator's grandmother pulls down the window shades. Grandmother comes upon a set of expressions that suits her perfectly, so she continues to use them long after they are out of fashion. Grandmother always complains about the children breaking the boughs of the redwood trees as they go down the hill in the afternoons. She sends one of them to fetch a specific sweater before allowing them to go downtown for Eskimo Pies. Grandmother listens to Mozart piously and prefers the weather to be seventy-two degrees with no breeze.
