Once upon a guitar

18 year old Cassandra has saved up her money for years. She doesn't want a phone, laptop,new clothes, or makeup. She wants that one special guitar that her parents can't buy her because, well becasue of her siblings. 9 siblings can be a wretched thing, so she saves her money for 3 years. When she gets to the store the first thing that she notices is that the guitar is being bought. At first she's angry, but then she sees who's buying it, now she's furious.
