How is Opal's mother described in the novel, What I Really Think of You?

Arnelle Watson Ringer, wife of Reverend Ringer and mother of Opal and Bobby John, accepts Fundamentalism in all its aspects. Devout in her beliefs, she is capable of speaking in tongues and dancing in the spirit. Once a pretty, one hundred sixteen pound woman, she has grown fat and likes to go barefoot at every opportunity. She is a secret listener to records of Dolly Parton, Loretta Lynn, and Crystal Gayle. Once a good singer herself, she no longer sings solos in public. She is fond of Good and Plenty candy and does domestic work at the home of a prominent family in order to help her family make ends meet. She loves her children unconditionally. She trains, counsels, and comforts them with love and understanding. A good-natured woman, she sometimes cautions her husband about the fierceness of his sermons.
