Laura Jalowitz is one of the pre-made townies who resides in Bitville, one of the neighborhoods shipped with The Sims Life Stories. She can be made playable by befriending and asking her to move in, or by marrying her. Laura's career and skills are randomized at the start of the game. She has the same facial structure and surname as Arianna Jalowitz from Veronaville. But there is no evidence that the two of them are related.
As far as personality, Laura is very active and quite playful. But she is very sloppy, quite shy, and somewhat grouchy. Laura's interests, lifetime want, and turn ons/offs are randomized at the start of the game. It is only referenced in the game files that she has no interests, lifetime want, or turn ons/offs.
