Sarah thought long and hard about how the stone worked. It appears that the cost of her age allows for there to be no monkeys paw shenanigan's. So she wished that for the rest of her life things would be taken care of for her with regards to the base hierarchy of needs. The stone glowed, and she felt the largest jump yet. From 5' 2" to 5' she became 15 years old. Just then she got an email that she won a publishers clearing house. Along with a sweepstakes to get lifetime groceries. It looks like the wish worked out, though I guess having to be on the young end of being a sophomore might suck.
Later she went to the house to find that the agent couldn't meet her there, but not to worry everything was all taken care of. It was a modest 3 bedroom suburban house. After arriving Sarah started registering for classes. And also picking out a wardrobe since everything was loose. I guess it's time to figure out where i'm going next.
