Harry: Uncle Vernon?
Vernon: What is it, boy?! Can't you see I'm trying to watch Top Gear?!
Harry: this is my friend Luna Lovegood.
Vernon: What?! One of your weird friends from that freak school?!
Luna: Hello, Mr. Dursley. You have a wonderful home. Harry told me you have a large knowledge of crime statistics and strong opinions on minorities. Would you have time to talk about per capita?
Vernon: Oh...oh my, what a charming young lady! Petunia, dearest, we have guests! Could you put the kettle on?! Now Ms. Lovegood, where would you like to start?
Luna: We could start with how unfair it is that those hook-nosed goblins hold disproportionate amounts of power in the banking system.
Vernon: HAHAHA! well, young lady, they definitely don't like it when you call them that, but you seem to have the right idea!
