"Aunt Marge?" Harry asked. "Is she coming here?"
"She is," Uncle Vernon confirmed. "And while I'm at it, there's a few things I want to get straight before she arrives on Saturday."
He nodded at Harry. "We've been telling her that you go to St. Brutus's Secure Centre for Incurably Criminal Boys. She doesn't know about any of your weirdness."
Harry twitched his wings, thinking about how much of his weirdness Aunt Petunia and Uncle Vernon didn't know about, then frowned.
"Why would you tell her that?" he asked.
"We've got to tell her something," Uncle Vernon barked. "You're away most of the year, we can't say you're going to the local comprehensive, can we, boy?"
"Well… I would have thought that if there was a place like that, it wouldn't let kids out for summer holidays," Harry explained. "You could have just said that I was going to a cheap school in Scotland on a Government grant because that way you didn't have to deal with me."
Aunt Petunia and Uncle Vernon exchanged glances.
"And I was going to be staying with someone else for half the holidays anyway," Harry added. "I could just leave in the morning of my birthday? That way you wouldn't have to deal with me, and nor would Aunt Marge."
That provoked a lot of grumbling, but eventually Aunt Petunia and Uncle Vernon agreed that maybe that would make a lot more sense.
