The Grand Hall

[livbeatles]

Sorry if this has been talked about before, but I haven't been around 
for a month or so, and not too much before that.  Anyways, on to my 
point.

I remember people mentioning how the Grand Hall's ceiling would be 
enchanted but when the mail came it was normal.  Did anyone else 
notice in the movie that Hermione said it was "enchanted to look like 
the night sky."  She only said night, not day.  So (to me) that would 
explain why the ceiling was normal when the mail came.  Did she say 
the same line in the book?  (I'd look myself but I'm at school and my 
book's not here)  Anyone agree?
