Your ex boyfriend, Cameron. Cameron was a dick. He dumped you with no apparent reason and hadn't spoken to you since. You were upset, but not 'I'm crying so much I can't breathe' upset. You always put your emotions into songs when you couldn't speak about them.
Colby was your all time best friend ever since kindergarten. And he knew you tended to write songs when you didn't feel like talking. He picked a fight with Cameron and they both got absolutely battered, while you were at the sidelines, screaming and crying for them to stop but they didn't listen.
Days passed, and they both still had bruises and cuts on their faces. You were taking extra care of Colby to make sure he didnt hurt himself worse, and Cameron walked past, giving you both sour looks.
Colby: "What's his deal?"
