"It's called Hogwarts." He said.
"Hogwarts?"
"Yes, Hogwarts. And there is a village next to it called Hogsmeade."
"Does everything in the wizarding world have to do with pigs?"
"No, of course not! There's Diagon Alley, and Godric's Hallow…"
"How do you know all this?"
"My mum told me."
"What about your dad?"
"He's a muggle."
"Muggle?"
"Like your sister. Not magical."
"And I am?"
"Yes."
"How can you be sure?" she asked suspiciously.
"Well, you just know. The way you can make stuff happen."
"Why can't Tuney be magic too?"
"She just can't."
"We can't make her magic?"
"No."
She sighed. "I don't want to leave her behind."
"I…you could write."
"Write?"
"Write a letter. To the headmaster. And ask if she can go too."
"Okay. But I don't have an owl."
"Use the muggle post. And Lily…"
"Yes Severus?"
"Don't tell her that it was my idea, all right? She doesn't like me much."
"Don't worry. I won't."
"Promise?"
"I promise."
