Cheeky
"So at Hogsmeade, I think I want to buy my weight in chocolate."
"Oh, really?"
"Yes. So I might need to borrow a bit of money from Sirius now that he's loaded. Unless you reckon Remus already has the entire stock of Honeydukes stored underneath his bed."
"And who says you're coming with us to Hogsmeade?"
"Please. Like you guys haven't been hinting at me to go with you all week."
"You, Miss Evans, are quite cheeky."
"Only when I'm right, Potter."
"So all the time, you mean?"
"Naturally."
