Explain

The house that Rose Mary inherits from her mother on North Third Street is very large. It consists of fourteen rooms, a piano, a set of china, and a front and back yard. Instead of sending her children to the neighborhood Catholic school, Rose Mary arranges for them to attend the out of district public school, Emerson. There, all of the Walls children are placed into gifted reading groups. The school nurse notifies the Walls that Lori needs glasses. Begrudgingly Rose Mary allows her daughter to wear the glasses, which are provided by the school, although she considers them a “crutch”. With the glasses Lori is able to see the world anew. She is moved to tears at the sight of all the details in the world that had hitherto appeared as blurs to her. After receiving her new sight, Lori decides that she will become an artist like her mother. In Phoenix Rex gets a job as an electrician and joins the union. The influx of money brings new amenities to the Walls home including bicycles for the children, telephones, a washing machine, and a record player. When roaches and termites begin to crop up in the home, Rose Mary and Rex refuse to use more conventional means of exterminating the creatures. Instead the family attacks the roaches using rolled up newspapers and Rex fills the termite created holes with empty beer cans.

Rex is fired three times before he is kicked out of the electrician's union. The inheritance money has run out and, once again, food is in short supply for the Walls family. Brian and Jeannette discover a warehouse dumpster full of chocolates which they eat whenever there is no food in the house. Rose Mary recruits the children for a shoplifting scheme to get Maureen new clothes for preschool and Rex discovers a sly way to withdraw twice as much money from the bank by making withdrawals from the teller and drive-thru window simultaneously. After losing his job Rex begins to drink heavily and he frequently returns home violent and angry, smashing dishes and trashing the house.
