Lawrence Lum is a pre-made teenage Sim, that is placed in the family bin with his mother, Lily Lum, and father, Theodore Lum. He is friends with both his parents. He dislikes children, but he also has the friendly trait. When his family is first moved into a neighborhood, Lawrence is 14 days away from becoming a young adult.
- When first played, he carries six copies of "Charisma Vol. 1: Fixing the Friend Problem", just like his mother.
- His name may be a pun on the word "slum" since his name fits into the word.
