[You're introducing yourself to Harry Potter] "So you're Harry Potter. Well, I'm Draco Malfoy. Here's a list of reasons why you should ditch the ginger and be my friend instead. I'm super-rich, I'm racist, and when I feel like it, I'm misogynistic too. My father was once a terrorist who served the dark lord that murdered your parents and I promise I'll treat you well if you ditch the glasses so you don't look like a nerd." 

"I know you're up to something, Potter, and I'm going to find out exactly what. It's my duty as your archnemesis to bring you and your gay friends down!" 

[You are cursing your rivals for humiliating you] "You fool! You'll regret the day you pushed Draco Malfoy into the mud! I will have my revenge! Crabbe and Goyle may look stupid, but that's because they have knuckles for brains! They are killing machines, Potter! And they are coming for you!"
