Forgive me if I'm being really slow on the uptake, but in the Snape's 
Worst Memory scene, why does Sirius wish it was full moon.?  Apart 
from being an extremely fraught time for one of his closest friends, 
what possible advantage can it be to Sirius?  I'd hate to think it 
was the excitement of being close to a wearwolf at that time.
Both Sirius and James remind me in this scene of Steerforth in David 
Copperfield, when he is taunting poor Mr. Mell.  A lot of people seem 
to like him too,  I can't think why.
