Lizzy is your twin sister.
Thanks to her immense popularity, you're basically safe from being the butt of any jokes at school, and most people will walk out of your way when you go down the halls just because you're related to the popular girl.
How did Lizzy get so popular? Not even you really remember... Also, your father is a teacher at the school who hates his job and does anything he can to not work, sooo... Let's just quickly say you two don't have to worry about bad grades. Heck, you could probably ask him if you could both stay home and he would say yes.
Lizzy: "Jeez, that stupid emo got really upset after I commented about her dead mom..."
Oh yea! When it comes to insults, Lizzy is UNMATCHED.
Lizzy: "Soooo... Hear any good gossip going around, sis?"
