Background
Gladys's past is mysterious like most other Sims. One day she meets Leroy and marries him sometime in the fall. After marrying Leroy, she has twins, Sylvia and Lawrence, with him. However, how she parents them is not known. It is also implied that she becomes an early grandmother when his son, Lawrence, has a son himself with a woman named Maggie. Initially, it's unknown how Gladys reacts to this until she explains she is furious.

By this point, Gladys and her husband are being taken care by Sylvia. One day in the late fall of some year, Gladys and her family head over to Lawrence's house for an anniversary party. She and Leroy are welcomed by their son, daughter-in-law, and grandchildren. After dinner, Gladys and Leroy are taken aside by her granddaughter, Karissa. Karissa reveals to them that she is pregnant, despite only being a teenager. Karissa then seeks advice. Gladys explains that both she and Leroy were furious with Lawrence, but they eventually forgave him. Gladys promises Karissa that her parents should react the same way. Karissa then thanks her grandmother.

By Harvestfest, Gladys receives a text from Karissa where she wishes her a Happy Harvestfest and explains that she's been kicked out of the house. It's unknown how this revelation affects her relationship with Lawrence.
