AN: So this is an AU. Sirius and Remus are 6 years old and meet in the supermarket. By the way, I don't own any of Harry Potter.
"Remus, would you please stop always running away?"
"But mum," Six-year-old Remus pleaded, his voice small. "I want to see the books."
Remus' mother sighed, leaning on the shopping cart.
"Alright. But don't stay for long, Remus, dear." She said, ruffling his hair and steering the cart to the canned goods. Remus squealed in delight and ran to the end of the aisle before turning to corner and running as fast as his little six-year-old legs could carry him.
He walked into the book aisle, making a small 'awww' noise as he eyed all of the books hungrily. Glancing at every one of them, they all seemed to be above him like a protective barrier of books, and all of the ones that he could reach were the ones that were his friendly companions.
Remus loved fantasy books. He loved the thought of another secret world that no one knew about it, the thought of magic and spells and powerful enchantments, and even the thought of the bad troublemakers that all of the good heroes defeated.
Ever since he was little Remus wanted to be a good hero who defeated the bad guys. But his mother told him to slow down and just enjoy his meaningless little life as a child (even though she didn't call life meaningless). But Remus didn't want to.
Soaring down the aisle of books, he ran smack first into a kid who cried out: "Ow!" And knocked backwards, holding his nose in his chubby little hands.
Remus immediately felt a rush of gratitude for the boy and backed away, sweating slightly. "I'm so sorry!" He apologized in a slur of words. The boy peeked through his fingers. "Are you okay?"
"I don't know." The boy murmured, and Remus was surprised to hear no trace of sobs or tears. He figured that he was okay and hadn't gotten hurt, but soon the boy let his hands fall to his sides, which revealed a bloody nose. Remus winced and stepped back a bit.
"Didn't that hurt?" He asked.
The boy shrugged. "I'm used to it."
Remus didn't ask why this boy – around his age – was so used to blood and pain. He shrugged it off and grinned hesitantly instead.
"I'm Remus." He said. The boy snorted and Remus looked affrontingly at him.
"Are you making fun of my name?" He asked.
The boy laughed slightly. He didn't bother to apologize. "It just sounds funny, that's all."
Remus furrowed his brow and crossed his arms. "It means 'leader of Rome'," He said proudly. "What does your name mean?"
The other boy huffed. "Sirius is a star. You're just some weak killed guy in Roman mythology."
"Serious? As in I am seriously listening?" Remus asked incredulously; he had never heard of such a name before.
"Don't make fun." Sirius said with a snarl, and put his hands on his hips. Remus pouted.
There was a pause while they both gave each other hard stares.
"I don't wanna talk to you anymore," Sirius said bluntly, and uncrossed his arms. "But I don't want to go back to my parents either."
"Why not?" Remus asked interestedly, dropping his snobby pose. Sirius looked at him critically.
"Because they don't like me." Sirius said, as though this was just another random piece of information. Remus looked sadly at him.
"That is very sad, Sirius." He said earnestly, looking at him with kind amber eyes.
"I don't really care." He strolled along the books carelessly.
"You don't care what you're parents think of you, or if you get scolded?"
"I used to. Not anymore." He said loftily, and shrugged. He picked up a book.
"My mummy likes me," Remus said, sharing. Sirius gave him a look. "At least I think so."
"Of course she does," Sirius said in a snappy manner. "Everybody's mums but mine love their kids."
Remus looked at the floor guiltily. "I'm sorry, Sirius. It must be torture, not feeling loved."
"It's not bad."
Just then, Remus heard his mother calling through the edge of the aisle faintly.
"That's my mum." Remus said, smiling at the other boy, who looked rather disappointed the he was leaving. It made Remus feel guilty that he was so alone. But he carried on and called back to his mother, waving at his supermarket-friend kindly before vanishing into his mother's clutches.
"Who was that boy you were talking to, Remus? I thought you'd be looking at the books."
"I was, Mummy," Remus promised earnestly. "But I ran into the boy and he started talking to him."
"That's nice, I suppose."
"Guess what, Mummy? He told me that his mum doesn't love him. Do you love me?"
Remus' mother leaned down and swept Remus into a small hug. "Of course, Remmy dear. It is unfortunate that some parents don't love their children." She gave a small 'tut' before taking Remus' hand in hers and walking along the cashier's register.
"Perhaps you'll see the boy again when we come back for shopping." His mother said kindly, and they both walked out of the store.
"Can we go to the park, Mummy?" Remus asked eagerly, tugging at his mother's flowery dress.
"It was raining earlier today. As long as it's not raining now, then okay. Get your shoes, dear." She fussed, tussling his hair. Remus smiled before thumping up the stairs to get his sneakers before he came back down again with his coat too.
"Come on, then, Remus. Hurry along, now." She grabbed hold of his hand and steered him out of the door, where it was humid and hot. Remus shed of his coat and just carried it securely under his arm until they reached the park, which was mostly empty because of the humidity. Remus ran toward the swings after giving his jacket and scarf to his mother.
He reached the dangly chains and saw his mother take a seat at one of the benches to talk with one of the other mothers, when he heard his name being called.
"Remus?" The voice said curiously, and Remus turned in the swings to see Sirius waving at him. He ran towards him and took a seat next to Remus in the other swing, curling his fingers around the silver chain carefully.
"Where are your parents, Sirius?" Remus asked, smiling at the other boy.
"They don't know I'm here," Sirius said, and he seemed to be smirking proudly. "I just ran over here."
Remus' eyes grew wide as he stared at Sirius incredulously. "Wow," He whispered. "I would never be able to run away from home."
"I didn't run away," Sirius explained. "I just came to the park. I'll go back again."
"Won't your parents be mad?"
"Yeah. I don't really care. They always are lately." Sirius started shuffling his feet at the damp grass and latched both of his hands onto the chain. He looked away from Remus.
"How far away do you live from here?"
"Brittany Forest." Sirius answered shortly.
Remus' eyes bulged into the size of plums. He stared open mouthed at Sirius, rather impressed. "But that's like… four miles away. Did you walk?"
"I ran," Sirius said. "I didn't want to get caught by my family." He explained, seeing Remus' puzzled expression.
Remus muttered an awed 'wow' again before smiling at Sirius. "Your nose is still bloody, a bit."
Sirius sighed. "My mum wouldn't fix it. I have to wait until it heals." He looked into the sky, where droplets were already falling gently. Remus kept on swinging.
"It must be terrible," Remus said, earning an inquiring glance from Sirius. "You know. Living at your house."
Sirius shrugged. The sky thundered as the rained harder onto the grass. Remus stopped swinging and placed his feet onto the wet grass and muddy dirt. Sirius smiled and sprang off of the swing in midair, shouting, and fell into the grass, all muddy and dirty. Remus gasped and leapt off of his swing, walked over to Sirius, thinking that he had slipped off of his swing, or something, and was hurt.
But just like in the supermarket, Sirius wasn't hurt. His jumping into the mud wasn't even unintentional. Laughing and gasping around, Sirius was rolling in the dirt as though rebelling his bad cleaning skills to his family. Remus couldn't help but stare disgustedly as Sirius played in the mud and let the rain wash it all off anyway. His mother started calling him.
He had to admire Sirius' rebellious attitude though. While Remus would never, ever, rebel against his mother, he would always try to work for his opinion. Sirius seemed to do that in just a much bolder, and harsher way. His mother was calling his name repeatedly now, somewhat worried, and while Remus tried to say "goodbye" to Sirius, the rain drowned his words and so did Sirius' business in the mud.
Remus ran back to his mother through the rain, his hair matted down and his smile still not fading, because for once in his life, he felt as though he had made a friend.
