"Tedious?" Percy regarded Malfoy with as innocent a look as he could manage - him being Percy and not one of the other Weasleys, he could manage a fairly convincing one. Who would ever believe the Ministry's pet prig could be anything less than innocent.
"I don't find it tedious at all, sir. I'm happy to do it. In fact, there are a few rather interesting stories I could tell you as well, about the importance of following this sort of procedure and the consequences of letting things slide." He folded his hands on the desk, as officious as anyone could ever want.
"Of course you're an important man with I'm sure a good deal on his schedule, so perhaps a deal: you'll not take up my time with mentions of my family, and I'll be as brief as possible in educating you about your own possession."
He peered steadily across at Malfoy - a trick picked up from his few years dealing with politicians. Protest nothing; imply displeasure without stating it outright, so he couldn't be called on anything. Percy wasn't Weasley enough to bluster or protest and feed into Malfoy's smug little pokes. But he was Weasley enough to want Malfoy to know that in his office, on his time, he wasn't a pushover who would take those pokes lying down.
