To avoid having to actually dress up (to go see Harry Potter 7b), I drew the dark-mark death-eater tattoo on my arm. But don't get me wrong, I'm not on the side of Voldie-voldie-voldemorte.
Also, interestingly, I've only read books 1, 6, and 7. Out of those three, Half-Blood Prince was by far my favorite. And I read the last two in Spanish, which some say doesn't count. Pero decirlo e' fome.
I think Rowling is leagues beyond me in her characterization. (And I include BACKSTORY as part of that.) But I think I could outdo her in plot. A little cocky, yes. We'll see if I can back it.
