Norma started out taking a bodybuilding program and later in the story goes to Community College and take a writing class. At that point she had stopped playing the organ (that Leroy bought her) and spent a lot of time going over her writing. The more time Leroy spends at home, the more he realizes that Norma is developing her own life and feels he doesn’t know her anymore (pg.235, third paragraph).
Her mother, Mabel also notices Norma changing and feels her trying to gain her own independence from Leroy. Mabel comes off as a very overbearing mother and spends a lot of time with her at the house. She visits the house often and inspects the house, letting Norma know what household chores she is falling behind on. Mabel also made a comment about a dachshund that ate a baby knowing that babies are a sensitive subject after catching Norma smoking pot.
At the end of the story when Norma tells Leroy she is leaving him, she also mentions her mom. Norma says, “ She won’t leave me alone - you won’t leave me alone. I feel eighteen again. I can’t face it all again.” This quote shows how she has felt stuck doing the same and still felt like she hadn’t gone anywhere in her life since she married Leroy. This is when she truly came to terms with this fact and gained her independence. I thought the symbolism of Norma walking away from Leroy on a serpentine brick path was clever because serpents symbolize knowledge.
