Who is Mrs. Hoodhood from The Wednesday Wars and what is their importance?

Mrs. Hoodhood is Holling's mother. Mrs. Hoodhood is much like Mr. Hoodhood in that she cares greatly about what others think. She smokes, but doesn't smoke in front of others. She keeps the house immaculate, keeps the sitting room nearly unusable, and makes sure her family is viewed in a certain way. She loves her children, but she allows her husband to run the household, sometimes to the children's detriment.
