   Okay here I am reading CoS again! This book is so confusing to me 
(possibly because I am trying too hard...). Anyway, this is my 
question: Why does Draco shout out "Enemies of the Heir, beware! 
You'll be next, Mudbloods."? I was under the impression that the 
chamber was put forth as a myth or was a closely guarded secret. How 
would Draco know that Mudbloods are next? I know later on he says "-
last time the Chamber of Secrets was opened, a Mudblood died." But, 
before that he says that his father wouldn't tell him anything about 
the Chamber.
 I think I am going to give up on CoS for clues and go on to 
enjoying reading PoA (My favorite so far. I cry every time Harry 
gets that last owl from Sirius allowing him to go to Hogsmeade!) 
again.
    One more thing. I just voted(?) on the last poll and was pleased 
to see my age group 35-39 with the most. I know it is early on 
though and this will most likely change.

Have a Happy Love Filled Day!   sad1199
