"Ha!" She looks at me, eyes wide, brows raised, lips curving with delight. "I knew it!" She laughs, tossing the fairy lights and jumping in glee, spinning and thrusting and pointing at me.

"I knew it, I knew it, I knew it!" she sings, punching her fists in the air. "Ha! I knew it!" She twirls.

I close my eyes and sigh, chiding myself for falling into her poorly concealed trap.

"You don't know anything." I glare at her and shake my head. "He was never my boyfriend, okay? He-he was just some new kid, who at first I thought was kind of cute, but then, when I realized what a total player he is, well, let's just say that I'm over it. In fact, I don't even think he's cute anymore. Seriously, it lasted like ten seconds, but only because I didn't know any better. And it's not like I'm the only one who fell for his game, because Miles and Haven were practically fighting over him. So why don't you just stop with all the air punching and hip thrusts, and get back to work, okay?"

And the moment I stop, I know I sounded way too defensive to ever be believed. But now that it's out there I can't take it back, so I just try to ignore her as she hovers around the room singing, "Yup! I so knew it!"

By Halloween night the house looks amazing. Riley and I taped webs in all of the windows and corners, and stuck huge black widow spiders in their middles. We hung black rubber bats from the ceiling, scattered bloodied, severed (fake) body parts all around, and set up a crystal ball next to a plug-in raven whose eyes light up and roll around when he says, "You'll be sorry! Squawk! You'll be sorry!" We dressed zombies in 'blood" covered rags and placed them where you'd least expect to find them. We put steaming cauldrons of witches' brew (really just dry ice and water) in the entry, and scattered skeletons, mummies, black cats and rats (well, fake ones, but still creepy), gargoyles, coffins, black candles, and skulls pretty much everywhere. We even decorated the backyard with jack-o'-lanterns, floating pool globes, and blinking fairy lights. And oh yeah, we placed a life-sized grim reaper out on the front lawn.

"How do I look?" Riley asks, gazing down at her purple shell-covered chest and red hair as she swishes her sparkly, metallic, green fish tail around.

"Like your favorite Disney character," I say, powdering my face until it's very pale, trying to think of a way to get rid of her so I can change into my costume and maybe surprise her for a change.

"I'll take that as a compliment." She smiles.

"As you should." I brush my hair back and pin it close to my head, preparing for the big, blond, towering wig I'll wear.

"So who are you going as?" She gazes at me. "I mean, would you just tell me already, because the suspense is really killing me!" She clutches her stomach in a fit of laughter, rocking back and forth, and nearly falling off the bed. She loves making death puns. Thinks they're hysterical. But mostly they just make me cringe.

Ignoring the joke, I turn to her and say, "Do me a favor?

She's down the hall and check out Sabine's costume, and let me know if she tries to wear that big rubber nose with the hairy wart on the end. I told her it's a really great witch's costume, but she needs to ditch the nose. Guys don't usually go for that sort of thing."

"She's got a guy?" Riley asks, clearly surprised.

"Not if she wears the nose," I say, watching as she slips off the bed and heads across the room, mermaid tail dragging behind her. "But don't make any noise, or do anything to scare her, okay?" I add, cringing as she slinks through my closed bedroom door, not even bothering to open it. I mean, just because I've witnessed that like a gazillion times doesn't mean I've gotten used to it.

I head into my closet and unzip the bag I've hidden in the back, removing the beautiful black gown with the low square neckline, the sheer three-quarter-length sleeves, and the super tight bodice that swells into shiny, loose folds—just like the one Marie Antoinette wore to the masked ball (well, as portrayed by Kirsten Dunst in the movie). And after struggling with the zipper in the back, I slip on my very tall platinum blond wig (because even though I'm already blond, I could never get my hair to go that high), apply some red lipstick, fasten a filmy black mask over my eyes, and insert some long, dangly, rhinestone earrings. And when my costume's complete I stand before my mirror twirling and spinning and smiling as my shiny black dress sways all around, and I'm thrilled with how good it turned out.

The second Riley pops back in she shakes her head and says, "All clear—finally! I mean, first she put the nose on, then she took it off, then she put it back on and turned to check out her profile, only to take it back off again. I swear it took all of my will not to just snatch it off her face and chuck it out the window."

I freeze, holding my breath, hoping she didn't do any such thing, because with Riley you just never know.

She plops herself onto my desk chair and uses the tip of her sparkly green fin to propel herself around. "Relax," she says.

"Last I saw, she left it in the bathroom, next to the sink. And then some guy called needing directions, and she went on and on about what a great job you did on the house, and how she can hardly believe you handled it all by yourself, and bippidy-blah-blah." She shakes her head and frowns.

"You must really love that, huh? Taking all the credit for our hard work." She stops spinning and gives me a long, appraising look. "So, Marie Antoinette," she finally says, her eyes taking a tour of my costume. "I never would've guessed. I mean, it's not like you're all that big on cake."
