Couple of silly detail-questions...

First, in CoS, Chap. 7, Harry is feeling guilty about missing the last 
game of the season in SS/PS, resulting in Gryffindor's "worst defeat 
in three hundred years." Now, I had always assumed that the Seeker was 
prohibited from touching the Quaffle. Assuming this is true, there's 
no reason why it should have been a particularly devastating defeat. 
That is, Gryffindor's Chasers and Keeper have always been more than 
able to keep up with the other teams, point-scoring-wise. So there's 
no reason that it should have been a particularly bad defeat, they 
should have just lost by around 150. (Assuming, of course, that the 
Seeker isn't allowed to become a temporary Chaser. If he/she is, then 
it's a whole new ballgame, with a power play type of situation.)
Second... When Harry first hears the voices, in Lockhart's office, he 
is completely confused as to what kind of entity could have DONE such 
a thing as been invisible and made noises... When he tells Ron, Ron 
has the same response, saying "But I don't get it - even someone 
invisible would've had to open the door." How come neither one of them 
automatically suspects a ghost? We have ample experience with ghosts 
being invisible and speaking, so why not just assume that it was one 
of them?
Had another one, of course, but I've forgotten it. Gotta start writing 
this stuff down...
