Misappropriation of Funs

Kenneth brings the case against his sister, Stephanie. Their parents give them money for their birthdays every year. Kenneth complains that Stephanie spends her birthday money on boring household items she'll be purchasing anyway. He says that she should use the money for something fun. She thinks there is nothing wrong with how she spends her money. Who's right? Who's wrong?

Thank you to Ken Small & Jon Barr for naming this week's case! To suggest a title for a future episode, like Judge John Hodgman on Facebook. We regularly put out a call for submissions.
