Chapter 1: His Best Friend

It was another scorching day in the Galveston heat, as Mary Cooper brought her five year old twins Sheldon and Missy to preschool. She wasn't having any problems with Missy, it was her son Sheldon who refused to even step foot in the building.

"But mama, they'll make fun of me in there!" Sheldon protested pulling on his mother's hand in the opposite direction.

"Missy you'll watch over your brother won't ya?" Mary asked looking down at her daughter, who smiled back at her.

"Of course mama!" Missy said. "I'll make sure no one picks on Shelly, and that he makes friends with someone at least."

"Now I'm sure to get picked on, my sister standing up for me?" Sheldon shook his head at his mother and sister's logic. "I'll handle myself thanks." He said taking his hand from Mary's and entering the building.

"Knew that'd work," Mary said smiling. "You run along now dear, have a nice day and tell Shelly the same." She said and Missy did so running in after her brother. "Please lord be kind, let him make at least one friend today." She glanced up at the sky, then sighed and walked back to her car.

Sheldon stopped dead as he entered the classroom, taking in all the other children that were there. They looked so messy and irritating, he scowled wondering why he was being subjected to this, he was a genius after all.

"Hey Shelly, mom says have a good day." Missy said smiling at her brother before leaning into his ear. "And try not to get kicked out please, I would like to stay in one school for once." Sheldon stuck his tongue out at Missy.

"That wasn't my fault, it was the older boys' fault." Sheldon said. "And don't call me Shelly!" He then proceeded to stomp off in a random direction, leaving his giggling sister behind. He turned to see if she was watching him, satisfied that she wasn't he turned back around only to bump into a girl with fiery red hair, causing them both to fall onto the ground. "Hey watch where you're going." Sheldon said grumpily.

"You were the one who wasn't watching," the girl said staring at him fiercely with the bluest eyes he'd ever seen. He swallowed nervously, he'd never thought that girls were particularly pretty, until this moment. "What are you staring at weirdo?"

"Sorry, it's just your eyes," he said. "They're so blue!"

"Is that wrong or something?" She asked red dusting her pale cheeks.

"No," he replied instantly. "I've just never seen such blue, pretty eyes."

"R-Really? You think they're pretty?" The girl asked twirling her red hair around her fingers. He nodded and her face lit up in a smile showing her straight white baby teeth. "My name is Nancy Michelle Adams." She said extending her hand to the little boy. Sheldon realizing they were still on the floor and stood up, then took her hand, helping her up.

"Why your full name?" He asked head tilted.

"Well my mother always says, when you meet a new friend say your whole name," Nancy said smiling. "She also said if they say their full name, you'll be friends forever," but he smile dulled somewhat after she finished.

"Um, I'm Sheldon Lee Cooper," Sheldon said shyly, his cheeks pink as her face once more lit up in a pretty smile.

"Looks like we'll be friends forever now Sheldon." She said giving him a quick hug.

"Wow Shell...um Sheldon, looks like you made a friend after all." Missy said walking up behind her brother, whose face now rivaled Nancy's hair.

"Shut up Missy, go away." Sheldon said scowling at her. Nancy just smiled and held her hand out to Missy.

"The name's Nancy," Nancy said.

"Missy, Sheldon's twin sister," Missy said smirking. "The better twin!" She laughed loudly. Sheldon became fed up with the nonsense his sister was spouting, and took his new friend by the hand leading her away from his idiotic sister.

"Sorry, she's too big for her britches sometimes," he said apologetically. "I'm the better twin, I'm a genius!" he said smiling triumphantly.

"Wow fancy," she said smiling.

(five years later)

Nancy walked into the school building, it was her first day of 5th grade, and she was looking for her best friend since preschool.

"Hey babe, looking good." A strange voice from behind her said, and she scowled as she turned to look behind her, hands on her hips only to find Sheldon with a Cheshire cat grin on his face.

"Why would you do that?" She asked shaking her head at him, but smiling all the same.

"Because I knew I could get your attention." He said smirking, Nancy smiled and pushed his shoulder.

"You're a jerk," she said jokingly. "Where's Missy?" She asked looking around for the other twin.

"She's already with her group of 'friends'" Sheldon replied rolling his eyes. "You know the giggling bunch of twits?"

"Yeah." Nancy replied smiling, Sheldon smiled back. He knew that Nancy was nowhere near as smart as he was, she was still his best, and if truth be told his only friend. "How was your summer Shel?"

"It was fine," he replied. "Other than George and Missy picking on me, I've been able to apply for college and I'll know by the end of the week if they'll take me."

"Applying for college already?" Nancy asked, although she wasn't shocked it was still a surprise.

"Well yeah, mom said with my smarts it would be simple to get in." Sheldon said smiling. "My 11 birthday is coming up in a few months and when next fall comes I'll be able to go to college."

"Oh, so I only have this last year with you?" Nancy asked her usually bright blue eyes dulled.

"Well yeah, you had to realize it was coming," Sheldon said concerned that his friend looked so sad about him leaving.

"I did, but well...I'd hoped that maybe we'd have longer together." She said trying to wipe the sadness from her face. The reason she was so sad, was for a reason she didn't want to tell him. They wouldn't actually have the year, but he didn't need to know that.

It was about halfway into the year, when Sheldon noticed that Nancy hadn't shown up for school. He wasn't sure if she was only out for the day, so he decided he'd call her later and see what was up when he got home.

When he was finally able to get home from school, he bypassed saying anything to his family and went straight for the phone, and just as he got there it rang confusing him. He picked it up. "Hello?"

"Hey Sheldon," Nancy's voice sounded depressed.

"Nancy, what's wrong?" He asked concerned. He knew there was something wrong.

"My dad got a new job." She said sniffling. "We're moving, he's already taken me out of school, we're moving all the way to California."

"California? Why so far away?" He asked shocked.

"He just said it's a better opportunity for us both," she said sighing into the phone. "I don't have too much longer to talk, the moving van will be here soon,"

"So this is it then?" Sheldon asked trying not to let the stinging in his eyes from turning into crying, so his siblings didn't tease him even more.

"Yeah, and I wanted you to know...I like you Sheldon, a lot...not that it matters anymore, we'll never see each other again." She said sniffling even more now. "Just thought you deserved to at least know that."

He could hear her father call her from the background, saying the van was there. "Well I think we will see each other again...I promise one of these days I'll live in California too."

"You're such a good friend Shel, I hope we do see each other again." She said. "Bye Sheldon."

"Bye Nance." He said and heard the click of her hanging up, and did the same himself.

"Who was that Sheldon?" Mary asked coming around the corner. She stopped dead when she noticed it looked like Sheldon was about to cry, and he hadn't done that since he was really young. "What's wrong hon?"

"Nancy had to move to California with her father." Sheldon said wiping his eyes trying to keep his tears off his face. "And I told her one day I'll live in California too...of course after college and everything."

"Of course Shelly," she said placing a hand on his shoulder.

From that day no one was allowed to touch Sheldon, and he became antisocial in the quest to find a way to California.
