How..

She looked at the model.
It was Billy. Naked.

"HIIIIIIIIIIII, MANDY." he greeted her.

If Grim was here he'd say "How did we miss dat?".
Mandy's eyes started to water by the sight of his bare body. She immediately tried to cover his image with her own drawing, what obviously wasn't any better. In frustration she crumbled it and moved her eyes away to Pud'n sitting on her left, who was surprisingly concentrated on his drawing. Pud'n managed to join the same class she was in, since it seemed he was smarter than everyone thought he was. But then again, just because you cry about everything doesn't mean you're dumb.

"What are you doing here, Billy?" Mandy dared to ask.

"Well, I drowned the real model in a spoon with yoghurt when I tried to open my locker, what wasn't a locker but ms. Stevens pet wig, so I got scared and runned around the school screaming "fire" for fun because it matches so well with the hystericaling running, but then everyone's thought there was a fire, and I said "No, there is no fire, I said it for fun", and then some babe said "Hey, you have nice teeth when you're screaming in horror, and our model just died", and that babe is the teacher over there, and that's how I saved Christmas."

The entire class was silent.
Mandy looked at the clock. 50 minutes had passed.
"Right on time, Billy. Now get dressed and get lost before I get sick."

The bell rang and everybody stood up. When Mandy was about to leave the classroom Billy already showed up behind her, dressed and well.
"Sooo, where are we going to?" he asked.

Mandy stared at him.
"You aren't coming with me."

"Why not?"

"Because we're no longer in the same class, in case nobody told you. And didn't you had a class to attend to yourself?"

"I don't know."

"Check your schedule, idiot."

"Why? I don't has any money to order something."

Before Mandy could reply she got paralyzed by a terrible stench that hit her "spot-where-a-nose-would-be". It smelled like a combination of many expensive deodorants and alot of cheap perfumes. Billy didn't seem to notice the smell, but he did start waving to the cause.
She turned around and recognized the cause, too.

"Yoooooooooooo..."

Oh no.

"..you're looking fine, girl!"

"REALLY? THANKS!" Billy replied with a smile.

"I SAID "GIRL", YO. ARE YOU A GIRL, YO?"

"Aren't we all in a way?"

"No!"

Mandy rolled her eyes.
"Hello, Irwin. Still fat and useless as ever, I see." she interrupted them.

Irwin winked at her.
"Chicks like to hold on to something, chick."

"Is that why girls look like camels under their shirts?" Billy asked.

"No, yo. Puberty pulls their chest."

Mandy didn't really have the need to listen to two teenage morons talking about the female body, so decided to "run for it". But both Billy and Irwin started to follow her, while having more disturbing discussions. She increased her speed, but they didn't leave her back.
Being with Billy alone was already a challenge, but in combination with Irwin it was getting close to unbearable. She did manage to get him off her back all Summer vacation long, though he did ring her doorbell a few times, but wasn't being a serious bother. Unlike the past few years.

"Don't you two have a class to attend to?" she growled.

"Nope, for the next two hours my schedule is completely blanco, yo..just like your perfect angelic skin, my love."

"And I don't know something about anything, so no idea." Billy followed.

"Relax, you're in the same class as me, yo. Where were you, anyway?"

"Presenting my pencil in Mandy's art class."

Mandy shivered. That joke alone was good enough to give this story an "M" rating.

"Cool. Sooo, where are we going to?" Irwin asked.

Just grand, another one. You'd think that Irwin would know better than Billy because he always had the title of "nerd", even though only his clothes and glasses made him look like one. But he obviously was no genius.
At least he stopped pretending; he lost the glasses, wore a loose yellow blouse, green pants, a small earring in his right ear, and had a little beard. He looked pretty adult-looking for a 15-year-old, but his behaviour never changed.

"There's no point in following me, we're not in the same class anymore." Mandy replied.

"We can walk you to the door?" Billy said.

"No, you're annoying, just leave me. I'll talk to you donkeys later."

Billy and Irwin stopped and watched her walk away. Irwin scratched his head.
"Strange, yo. Usually she doesn't mind us folowing her."

Billy shrugged.
"She probably hates me because I gave her a kissy last night."

"Oh."

"..."

"YO?"

"Yo." Billy echoed.

"No, you kissed Mandy?"

"..Yeah, last night in her room."

"In her room? At night? WHY?"

"I..don't..know?"

Irwin lost his temper. He grabbed Billy by the shirt and pulled him into the air.
"WHY. WHY WOULD YOU DO SUCH A THING, YOU KNOW I LIKE MANDY."

"EEK! I DON'T KNOW!" Billy cried.

"You'd better break up with her before I pound yo face, yo!"

"WHAT, MANDY IS NOT MY GURLFRIEND! And..if you think she is then why are you so angry?"

"Well, I didn't think you two actually did something. No one does."

Entire Endsville thought Billy and Mandy had a relationship, but indeed no one could even imagine them holding hands. It was a strange thought, but everyone was thinking it.
Before Irwin was about to punch him they heard a teacher calling from the other side of the hall:
"Hey, what's going on over there?"

"Oh, eh.." Irwin stuttered, and put Billy back down on the floor. "I was just threatening my best friend for making out with my love interest, sir."

"Yeah."

"...Okey." the teacher said, and carried on.

Irwin turned back to Billy.
"Just stay out of her way, yo!"

"Yep."

"...DON'T JUST SAY "YEP", DOESN'T MANDY MEAN ANYTHING TO YOU?" Irwin scolded him.

"But you just said.."

Irwin raised his hand suggesting him to shut it.
"You make me sick!...Yo!"

He snapped his fingers and walked away. He entered a room that said "Janitor", and 5 seconds later he came back out, looked at Billy, snapped his fingers again, and moved on like nothing happened. It wasn't a very intimidating exit, but Billy knew he wasn't really angry with him. This wasn't the first time they got in a "fight", so his outburst didn't worry him.
He turned around and decided to follow Mandy's tracks to her classroom. It's not like Billy didn't hear Mandy's "no", it's just that he didn't listen. He decided to join all her classes the rest of the day, and even after every teacher told him he was in the wrong class, he was certain he belonged there. He didn't know any better; he was never seperated from Mandy before. He simply didn't want to acknowledge it because he never could handle change very well.
After a while Irwin joined in, too, just to keep an eye on Billy and to be with "his little cream pie".

At the end of the day Mandy managed to get rid of Irwin, but was still stuck with Billy. Being her neighbour and friend, that's no surprise, but she still felt awkward being around him and just wanted to be alone for the rest of the day.
Then again, now Irwin was gone this would be the right time to ask him about Grim's spell. But was she really able to do so without reminding him of the kiss?

She looked at Billy, who was cheerful as ever and in the middle of telling one of his famous, uncalled-for life experiences. He made his life sound it was one great adventure after another. But how lame these "adventures" might were in reality, it still made anyone else's life sound grey and dull. Even Mandy's. Somehow you could do nothing but adore his talent of putting on socks sound exciting.
Mandy just kept on staring at him till the moment she could no longer understand the words he was saying. She only saw his lips moving and heard the mere noise of his voice. It was like she was daydreaming.
Was she really that bored by him, or was she mesmerized?

He was so into his story..maybe she shouldn't ask him about the curse. It would only be rude to interrupt him, wouldn't it? And Grim would be there any minute, and asking him for any clarifications instead of Billy would save her from any possible embarrasment.

"Hey!"

She awoke from her trance.
"What?" she mumbled slightly confused.

"If I can eat at your place tonight!"

"..Better not, we're eating rat today."

"Wow, you're French?"

"..But I'd like to take Grim off your back tonight. He can have dinner at my place."

"That's okey, Grim can stay with m.."

"I SAID: I'd like to take Grim off your back tonight." she hissed.

"Oh. Yes. But Grim promised we were going to make our own boardgames today." Billy pouted.

"Sorry I'll have to take your best buddy from you, but it's my turn."

"Oh, he isn't my best buddy." he smiled.

"Really, then who is?" Mandy asked, trying to sound interested.

"You are my best buddy, silly."
