Sharon Foss is a pre-made adultSim from Four Corners, one of the neighborhoods shipped with The Sims Life Stories. She is the sister of Jane Harlow, and the aunt of Riley Harlow. During the course of the story Sharon is revealed to be in possession of a considerable fortune, which she made on the stock market. She also mentions having received Military training at some point, although how and when this came about is left humorously vague.
She is revealed to be unemployed when she becomes playable in free play mode of Riley's story, presumably because her vast wealth means she no longer has to work. Sharon lets Riley stay at her house, 10 Hyacinth Circle, in Four Corners to get back on her feet, but then goes away on a business trip soon after Riley's arrival. She is the second richest Sim in The Sims series. The richest Sim is Vincent Moore, and the third is Mortimer Goth.
While she is away, she is kidnapped by Dylan Kincaid and Agora Tchotchke. An e-mail is sent by Dylan to Riley in Aunt Sharon's name. Dylan and Agora planned to get Aunt Sharon's money, then do away with Riley and Sharon. Sharon escapes Dylan's basement, and calls the police. Dylan is arrested, and after that Riley marries Mickey.
Sharon gives her the house, leaving soon after to go on a date with a man she met on the internet. After the story is finished, Sharon appears in the neighborhood family bin, although there is no mention of her supposed boyfriend. When Sharon is first moved onto a lot, she is 5 days from being an elder. She has the Knowledgeaspiration and the Sagittariuszodiac sign. Despite being kidnapped by Dylan in Riley's story, when free play mode is unlocked, Sharon and Dylan have no relationship with each other.
Although Sharon is Riley's aunt, they are not on the same family tree. This is because her sister (Riley's mother) is not shown on the family tree either, therefore she can't be shown. Sharon does not appear in the Free Play version of the neighborhood. Sharon bears a passing resemblance to Bianca Monty from Veronaville. In Aurora Skies from The Sims 3, there is a street with Sharon's last name, the Foss View Road.
