Who is Mrs. Donna Spring from Whatever Happened to Janie? and what is their importance?

Mrs. Spring is not at all like Mrs. Johnson. She is not as concerned with appearances or clothing, likely spending the money they have between their six children instead. She is a little on the larger side, aptly described as chunky, and beginning to go gray. Unlike Jennie and Mrs. Johnson, she pulls on a shirt and sweater that don't necessarily match perfectly, straps on her utilitarian watch and is ready for the day.

Mrs. Spring is a talkative woman. She enjoys telling and hearing the stories that make up the family's day. She is interested in every ball game, book report or exam that any of her children are taking and laughs and teases them about it all. She always seems to be going at high speed, getting through her own day, and then organizing and attending the after school activities of her children. She always seems to be slightly out of breath.
