My favorite moments:

[Geoff Bannister]

Geoff;
I have two sorts of favourite moments. One type 
is the sort where I laugh out loud - much to the 
annoyance of my other half who isn't into the 
books; the second sort is one of those serious 
moments which stick in your mind forever.

Two examples, first one of my favourite funny scenes:

'"Yes, as I was saying, Potter, Professor Lupin thought 
you showed a pronounced aptitude for the subject 
and obviously for an Auror -"

"Did you not understand my note, Minerva?" asked 
Professor Umbridge in honeyed tones, quite 
forgetting to cough.

"Of course I understood it," said Professor 
McGonagall, her teeth clenched so tightly the words 
came out a little muffled.

"Well, then, I am confused... I'm afraid I don't quite 
understand how you can give Mr.Potter false hope 
that -"

"False hope?" repeated Professor McGonagall, still 
refusing to look round at Professor Umbridge. "He 
has achieved high marks in all his Defence Against 
the Dark Arts tests -"

"I'm terribly sorry to have to contradict you, 
Minerva, but as you see from my note, Harry has 
been achieving very poor results in his classes with 
me -"

"I should have made my meaning plainer," said 
Professor McGonagall, turning at last to look 
Umbridge directly in the eyes. "He has achieved 
high marks in all Defence Against the
Dark Arts tests set by a competent teacher."

Professor Umbridge smile vanished as suddenly 
as a light bulb blowing.'

And a sentence which always speaks volumes to 
me:

'The sun had set before he realised he was cold.  
He got up and returned to the castle, wiping his 
face on his sleeve as he went.'
