Ah! Carees Advice! That's It!
Now I remember why I enjoyed it so much. Adding to Fred & George's departure, we also had the very very funyn little shojwdown between Umbridge and Mcgonagall (which coincedentally pretty much told us that Harry is going to become and auror, due to the fact that Minerva told him she was going to help him and dedicate all her time to personally
making him into an auror. Lol... oh that was funny.
Ok this is just a random one-liner from OoTP The Centaur and the Sneak, which I just think is awesome. Just the way it is written, I can imagine someone saying it in such a funny way. I laughed out loud when I read this. Just imagine DD blowing away like four or five heavily trained members of the Ministry like that! And then disappearing in a whiff of smoke. I think this is completely adequate for that moment: "I disagree with Dumbeldore on many counts... but you cannot deny he's got style..."
That just sums up the book for me!
(Adding the my fav. chapters, I must also say that my favourite series of consecutive chapters are chapters 25 to 29, in OoTP. They are some of the funniest I've ever read. The serious one's might be in PoA or OoTP at the end, but these are: The Beetle at Bay, Seen and Unforeseen, The Centaur and the Sneak, Snape's Worst Memory, and Career's Advice. There are some grand pieces of writing in there!
