Page 166 in the first paragraph it says and I quote, "A few minutes passed; Harry heard the door close but remained bent double..."

Now follow down to the second paragraph. Again I quote, "Harry hurried across the room, closed the door, then returned slowly to his bed..."

I know someone will point out that it's a magical house, but I really doubt that magic would prevent a door from closing. If anyone has a logical reason for this error please submit it.
