My son has just pointed out to me what may be a small mistake in 
Chapter 30 of Order of the Phoenix.
On page 602 it says
"They found seats in the topmost row of the stands".
On the following page it says
"Apparently he (Hagrid) had squeezed his way all along the row behind"
Not in any way important, it's just that at 13 you feel delighted to 
have caught out an adult in a small mistake. Or are we mis=reading?
