"You? You look like the poster boy for Slytherin!" James Potter laughed as Sirius Black stood beside him. Lily scowled. "Didn't you say you wanted to be in Gryffindor? It's not 'brave' to judge people based on their looks!" Severus shook his head. "It's true. I don't want to be in Slytherin. I'd be fine with just about anything else…" Even Hufflepuff. Even Hufflepuff for Lily.
"Don't sweat it," Sirius Black piped up, "If anyone's meant to be in Slytherin it's me. I hope my cousin chokes on her good for nothing tongue when she sees I'm put in Gryffindor." James Potter turned to look at him. "Yeah, come to mention it, didn't you say your name was Black? Well, I'm all for making some Slytherins get their knickers twisted, I hope you both get put in Gryffindor."
Snape did too.
Lily smiled, "Then we can all be friends. I might forgive you for insulting Sev if you promise!"
