Holly's sense of entitlement drives me crazy. Of COURSE she deserves a Firebolt after all the stress she's been through! (Of course, Harry has been through much MORE stress at this point, since he still thinks Sirius is out to kill him...)
And I also hate her whining about the Patronus Charm. She's going on about "Why does it have to be so HARD? I should be able to do this right away so that I don't have to waste my tiem actually struggling with the spell and my emotions, like a normal human being!"
Not to mention the relentless Gryffindor bashing...
UGH! She's such a jerk!
