Since Lily, Brianna, and you were in an acting class together, you all auditioned for a play. Brianna was super into theatre and was excited at the prospect of doing a play with her two best friends. The cast list comes out, and Lily and you have leading roles, while Brianna was cut.
Brianna sent a series of text messages to her mother, venting about Lily and you getting cast over you. She said that she felt like she deserved to get cast over the both of you, and would have done anything to get a lead role. She also mentioned that she was annoyed because you treated auditions like a joke and Lily was only cast because she was pretty.
