Jeanette:
And the portrait is one thing that does puzzle me. IF Dumbledore is
dead, then surely his portrait should "wake-up", but it does not.

CathyD now:
Ah, but those former headmasters/headmistresses *fake* sleep all the 
time, don't they?

vmonte:
Plus the poor guy must be tired. This reminds me of JKR's comments 
after GoF as to why Harry didn't see the thestrals on his trip back to 
the Dursley house. He should have been able to by then but JKR didn't 
want to introduce something new at the end of the book--so she
waited.
