A Susan
A Susan is a hot, kind, and sweet girl who will be your best friend forever. But if you do something stupid, she'll flip out and it'll be a total nightmare. She's super pretty, but she doesn't realize it. She's also super lucky if she has a guy who loves her like crazy.
"You messed up my lunch? I'll mess up your life.", Susan, in the middle of a food fight.
"I'm the best friend, but I'm also your nightmare.", Susan, being dramatic.
"You're my best friend, but I still hate you sometimes.", Susan, being real.
