Theresa Ying is one of the pre-made teenage townies who resides in Bitville, one of the neighborhoods shipped with The Sims Life Stories. She can be made playable by aging her up with another teenage Sim, and then befriending and asking her to move in, or by marrying her. Theresa is employed in the Criminal career as a Pickpocket at the start of the game. She is a C student enrolled in Public School at the start of the game.
As far as personality, Theresa is very outgoing, quite nice, and somewhat playful. But she is very sloppy and lazy. When it comes to her skills, Theresa is on her way towards maximizing the creativity skill, but she doesn't have a particularly high level in any of the other skills. She is mostly interested in Paranormal, Work, School, and Sci-Fi. Theresa has the same facial structure as Marion Pearson.
