Valentine's Day is one of those days where "potentional couples" get bothered by their surroundings. Luckily for Mandy that day was now far behind, and Summer Vacation would officially start as tomorrow.
Billy will be send to Summer camp, so this would be her best vacation yet; nobody to pester her about their "relationship", and it's one moron less to take care off. She would be able to use these months to work on her projects in peace.
Billy already started packing when coming home from school, as the bus would be there soon to pick him up. With alot of struggle Grim and Mandy found it in their hearts to go outside to wave him goodbye.

"...And when I return I'll be 15, isn't that just funny?" Billy yelled in excitement.

"That's what camp does with you, it sucks your life away." Mandy said in a most serious tone.

"If it sucks my life away, then why does a year get added to it everytime I come back?"

"Billy.." Mandy said, "That doesn't make sense, I am not even going to answer that."

"Now get lost already, you bignosed freak" Grim said, and went back inside to watch Will & Grace on the television. Obviously he was even less interested in the conversation.
Billy came closer to Mandy with the intention to give her a hug, but she pushed him away before he could do so.
"Hey, what's the meaning of this? You went to camp before, just go."

"But not all Summer..what if I get homesick, and Mandysick, and Grimsick?"

His once cheerful face turned sad. He loved camp, but he's never been away from Mandy's side longer than a day, the least.
"..Maybe I should just stay here."

Mandy's eyes widened. "No no, go, you'll have a great time."
No way doofus was going to ruin her plans, she thought.

"But what about my Grim-Mandy-homesickness?"

"I'll tell you what, Billy, why don't I let Grim visit you so now and then?"

"What in the..!" said a familiar voice from out of the house.

"You coming with?" Billy asked.

"No. If you have anything important to tell me or to give me, just hand it over to Grim."

Mandy told him that she was too busy to hang out with him at the moment, and surprisingly enough Billy understood and didn't start a racket about it. He was satisfied enough with the alternative Mandy suggested. Unlike somebody else.
Billy entered the bus and waved like a maniac from behind the window. It was good for Mandy to see the simple minded boy was that easy to cheer up and to be off her back at the same time.

As expected Grim immidiately started complaining as soon Mandy entered the house: "I don't want to play homing pigeon dis vacation, they're showing reruns of me favourite shows, I don't want to miss any of it!"
Of course she wasn't too interested in what he had to say and instead ordered him to paint the house. Just for the heck of it.
Grim started mumbling to himself how "he agreed to be their best friend forever" and not their "best slave forever", but did it, nevertheless.

While he was out of her way, Mandy went upstairs to her room and locked the door. When looking at her cellphone lying on her nightstand, she noticed she had 80 new messages, all from Irwin.
"I just bought this phone yesterday and activated it this morning, how did he get my number?"

Mandy was never too fond of following crazes, but since everybody in her class had a cellphone, Billy also purchased one and convinced her to get one, too. This was 2 years ago, though. But she thought it would be handy to have one. Especially now.

She rolled her eyes, and deleted all the messages without reading them. Then she sat down on her bed and continued writing in some notebooks that were already there waiting for her on her pillow.
"..This year is going to be the start of The New Age." she said to herself, and a satisfied, evil grin appeared on her serious face.
"I finally have the opportunity to put my plans into practice. I've waited 15 years for this, it cannot fail..!"

Meanwhile Grim was watching her through the window with a concerned face.
