Disclaimer: I only own Vivi. However, I also own a copy of the movies and a Harry Potter tank top.

Fun fact of the day: Vivi's in Gryffindor. Surprised?

Buy a cheap muggle cell phone and make it go off every hour

"I'm surprised they haven't kicked you out yet." Harry said while Vernon drove home from church.

"It's because they're gonna afraid I'm gonna hex them or blow up the house." Vivi replied. "Right Vernon?" she said leaning forward.

Vernon let out a grunt. Just as he drove past a mall outlet, Vivi cried out that she needed something from RadioShack.

"What could you possibly need?" Petunia asked as Vernon stopped at RadioShack.

Vivi opened the door, said "Don't even dare leave me here," and disappeared inside.

"Hello." The guy at the cash register said.

"Hey." Vivi replied. Vivi scanned the shelves for what she was looking for. She picked up an MP3 Player, charger, and a Samsung cell phone.

10 minutes later, Vivi came out of the store. She was carrying a bag.

"About time." Vernon commented.

"Relax." Vivi replied. She buckled her seat belt. "I couldn't decide what to get."

Dudley looked at the bag curiously. Vivi pulled the bag closer before Dudley could try to peek inside.

"Dudley, Mr. and Mrs. Gaston are coming for business dinner tomorrow." Vernon said. "You will be opening the door and taking coats."

"I'll talk to Mrs. Gaston." Petunia chimed in.

"2nd year all over again." Harry muttered to Vivi.

"You two will stay out of sight." Vernon said looking in the review mirror.

"Out of sight but not out of mind." Vivi pointed.

Vernon ignored her and parked the car. Vivi ran into the house and up to her room. Harry waited about 10 minutes before going to Vivi's room.

"Get the card?" Vivi asked.

Harry held up Vernon's credit card. "Check. What do you need it for?" He asked.

"For way number 4 on the list."

"Oh, that's right."

"I'm gonna download a ringtone with this credit card."

Harry handed his friend the card. Vivi surfed the web and found the perfect ringtone. She punched in the card number. She checked to make sure the phone actually downloaded the ringtone.

"Perfect." Vivi said as the ringtone played.

"Turn it off!" Harry pleaded with his ears covered.

Vivi smirked and stopped the ringtone. "Brilliant isn't it?" she asked. "Now, we just have to figure out where to put this."

"Will that go off every hour?"

"Leave that part to me."

Vivi messed around with the phone. She tested the timer then she set it for the appropriate time.

"Now Harry, we need to put this somewhere where the Dursleys can hear it from anywhere in the house." Vivi said to her friend.

"How about the air vent?" Harry suggested.

"You're going somewhere with this."

"How are we gonna get it up there?"

"Get me a screwdriver then lift me up to the air vent."

"Why do I have to life you up?"

"I'm lighter than you."

"Good point."

Harry handed Vivi the screwdriver. He cupped his palms together. Vivi stepped into his hands before being lifted up.

"You're going to have to hold the nails." Vivi said to Harry. "Just don't lose them."

The cell phone was put into place. The vent was put back on the wall.

"Phase one complete." Vivi said happily. "See you in the morning."

"Night Vivi."

"Remember your roles." Vernon said the next day. It was one and one more hour until the guests arrive. "Dudley?"

"I'll open the door and take the coats." Dudley recited.

"Petunia?"

"Waiting to welcome Mr. and Mrs. Gaston. I'll start a conversation with Mrs. Gaston."

"Excellent." Vernon turned to Vivi and Harry. "And you two?"

"Upstairs." Harry answered.

"Out of sight but not out of mind." Vivi added.

"Get your feet off of my table." Petunia demanded.

"No, you're not the boss of me."

"What will it take to make you stay upstairs?" Vernon demanded.

"Give me 100 dollars and some cupcakes."

Vernon clenched his fists and forced a smile. "Petunia, please make Vivi some cupcakes. What kind do you like?"

"Chocolate with chocolate icing."

Vivi got her cupcakes just as the bell rang.

"Where's my 100 dollars?" Vivi asked.

Vernon handed over a 100 dollar bill. Vivi snatched it and ran upstairs.

At exactly 2:30, something interesting happened.

But don't tell my heart, my achy breaky heart
I just don't think it'd understand
And if you tell my heart, my achy break heart
He might blow up and kill this man
Ooo

"What in the world?" Mr. Gaston asked.

"Turn off the radio, Dudley." Vernon barked at his son.

Dudley padded over to the radio. "It is off." He said to Vernon.

An hour later, the singing could be heard again. Petunia went over to the window and looked around.

An hour later, after hearing achy breaky heart, Vernon excused himself and went to Vivi's room. Vivi was talking on her phone. (A/N: Not the one in the vent.)

"You're ruining me girl." Vernon hissed.

"Hang one a minute." Vivi said into the phone. "What are you talking about Vernon?" she asked Vernon.

"You know what I'm talking about."

"Oh Vernon, why do you think I'm doing anything?"

"Just stay here." Vernon left the room.

Vivi waited until the door was closed. She said, "Come on out Harry."

Harry came out of the closet. "How many more times until we can turn of that phone?"

"Until the batteries die or Vernon's face is purple."

"Brilliant. I'm heading back to my room."

"Later."

"You too."

Vivi turned back to her phone. "Nah, just driving my host family up the wall." She said. "Cause it's fun."

At 4:30, Vivi knocked on the wall. Harry knocked back. Vivi put ear plugs in.

But don't tell my heart, my achy breaky heart
I just don't think it'd understand
And if you tell my heart, my achy break heart
He might blow up and kill this man
Ooo

By then, the Gastons were about ready to leave for home. The moment they left, Achy breaky heart was heard.

"POTTER! VIVI!" Vernon screamed.

Vivi just smiled and bit into a cupcake.
