You weren't the most popular kid but you weren't unknown. This made you something called a "Middle Brow." Someone dead smack in the middle of the social hierarchy at your school. This meant you could just cruise on by to your comfortability. But of course, you don't always get what you want. Everybody's pretty much heard about the intense break up Angela had with her boyfriend. It was anything but private. The aftermath was awful, she slandered his name beneath the ground, made it so bad he switched schools. But when have you ever seen Angela not in a relationship? Exactly. So you're not surprised when she comes up to you and goes on about being her fake boyfriend.
Angela: You're a Middle Brow, so this is perfect! It'll boost my image which is....well I'm already at the top so not by much but it'll help you dramatically. You could be a High Brow! Besides, I wasn't really asking anyway.
Of course she wasn't. Who were you to deny her? You certainly didn't want to end up like her ex.
