Como Dumbledore uma vez explicou Harry, as pessoas geralmente aparatam na frente da casa (ou ao redor da casa, pelo menos não dentro dela) que estão visitando por duas razões:
- é rude aparatar diretamente na sua cozinha host
- a maioria das casas tem encantos anti-apparating
"Professor, why couldn't we just Apparate directly into your old colleague's house?"
"Because it would be quite as rude as kicking down the front door," said Dumbledore. "Courtesy dictates that we offer fellow wizards the opportunity of denying us entry. In any case, most Wizarding dwellings are magically protected from unwanted Apparators.
(Half-Blood Prince, Chapter 4 Horace Slughorn)
Mas sabemos que é possível aparatar dentro do Largo Grimmauld: George e Fred costumavam aparatar de um quarto para o outro:
“We have,” said Hermione quickly. “We’ve been decontaminating this house, it’s been empty for ages and stuff’s been breeding in here. We’ve managed to clean out the kitchen, most of the bedrooms, and I think we’re doing the drawing room tomo — AARGH!”
With two loud cracks, Fred and George, Ron’s elder twin brothers, had materialized out of thin air in the middle of the room.
(Order of the Phoenix, Chapter 4, Number Twelwe Grimmauld Place)
E sobre a polidez ... Quando apenas Rony, Hermione e Harry estão na casa, é realmente rude um deles aparatar dentro da casa (ou até mesmo para Lupin)? Vale a pena correr o risco de aparatar na escada, às vezes tropeçando e deixando a Capa da Invisibilidade escorregar, enquanto os Comensais da Morte estão observando o lugar?
Lupin explicando que ele "teve que" aparatar no primeiro degrau e contar sobre os Comensais da Morte:
“Yes,” said Lupin, “but we’re all being watched. There are a couple of Death Eaters in the square outside—”
“We know—”
“I had to Apparate very precisely onto the top step outside the front door to be sure that they would not see me.
(Deathly Hallows, Chapter 11, The Bribe)
Harry quase sendo visto pelos Comensais da Morte enquanto volta:
Meanwhile, inside number twelve, Harry had just entered the hall. He had nearly lost his balance as he Apparated onto the top step just outside the front door, and thought that the Death Eaters might have caught a glimpse of his momentarily exposed elbow.
(Deathly Hallows, Chapter 12, Magic is Might)
Então, explicando sobre isso para Ron:
“They nearly saw me coming back in just now,” Harry said. “I landed badly on the top step, and the Cloak slipped.”
