Disclaimer : I do not own Harry Potter (but I wish I could own Sirius Black !)

AN: Well that's a very first. I have written Book 5 in my own way before it came out but I wouldn't dare publish it. I'm not a native speaker of English so please feel free to make me notice any mistakes I made. It's not a big chapter but I hope it will interest someone ! Please review !

"Come on, Sirius, move along, I don't have much time!" said an annoyed voice over the handsome, black-haired young face of Sirius Black.

Sirius breathed heavily and looked around.

It was the 1st of September and he had just entered Platform 9 3/4 for the first time. His eyes sparkled with awe as he looked the smoke rising from the big black and red train –the Hogwarts Express. Wizarding families were all around, bidding goodbye to their children, while Muggle families looked startled, keeping their children close to them as they waited for someone to help them.

"Well, son, I think it is time I leave you", said the annoyed voice again.

"Dad, wait!" answered Sirius, who, at 11, wanted to get a little comfort from his father who seemed more than annoyed of being here.

"Sirius, I'm in a hurry, you know your uncle's waiting for me back home. Besides, you've got to learn coping with new situations. You're a Black, my son. Blacks are not cowards and they can figure out things by themselves. Goodbye."

Without more explanation, Sirius' father left him alone with his luggage and disappeared.

"Are you alone?"

Sirius was interrupted in his reverie when he heard the voice of a young boy who had just popped his head inside the compartment he had settled in, all alone.

"Yes, you can come and sit if you want" Sirius said, looking more closely at his new companion.

The boy wore glasses and had a proud and self-assured look about him. He sat down opposite Sirius and extended his hand:

"I'm James."

Sirius, surprised at the boy's eagerness to make friends with him, took his hand in his:

"Sirius."

Sirius took a look at the boy's long robes and assumed he was from a wizarding family.

"So you're not from a Muggle family, huh?" He asked to start a conversation.

"Nope. You?"

Sirius looked again at James. He sure seems to be sure of himself, he thought. And not shy with that.

"No", Sirius finally answered. "You surly don't know my family for assuming I could be a Muggle", he added without thinking.

"Why are you saying that for?" asked James, curious.

"Nothing" Sirius answered quickly, wishing he could take back what he just said.

Inside Sirius' head:

What a stupid thing to say, you silly boy! Now he's gonna think you're one of these intolerant, purist people! You don't wanna spoil your one chance to make friends with someone! Must be more careful about what you say!

James looked at Sirius and took him out of his reverie once more:

"Now will you excuse me if I'm not much a conversation person today. My family threw a big party for me yesterday, first boy going to Hogwarts and all these traditions, you know. I went to bed late and I couldn't sleep, with all the exciting things ahead of us. They wouldn't tell me about this Sorting Ceremony though, so I must get some sleep just in case it's something physical, you know"

"Yeah, sure", answered Sirius, still amazed at the way his companion was at ease with someone he didn't even know yet.

James put his legs on the seat and rested his head on the window, pulling out his glasses and closing his eyes. The next minute, he was already asleep.

Sirius looked at him again and inspected him closely. For a boy of 11, James had solid muscles, he noticed. Must be the athletic type. Maybe he likes Quidditch? That would be great.

Sirius smiled to himself at the thought of Quidditch, the only thing that linked him to his family. He and his younger brother Regulus shared the passion of the Wizarding sport and that was the only thing his parents seemed to value about him. Regulus was in good terms with Mr and Mrs Black, but Sirius could not stand a conversation with them, unless it was about Quidditch. They never took the time to share a moment with their sons, always highly occupied as they were with their image in the wizarding society. For them, the only important thing was being well thought of among the wealthiest wizards. They never took care of their children and Sirius and Regulus were often left with Kreacher, the stern-looking house-elf, to spend long days at their family mansion. Sirius often spent time on the square in front of the house and had once the idea to go speak to the Muggle kids playing there, quickly making friends with them. He spent weeks with the little Muggles, careful to go out only when his father was away. But Mr Black caught him and locked him in the house, forbidding Sirius to talk to Muggles again.

Thinking about all these new things he was to live in the wizarding school of Hogwarts, Sirius was almost relieved to leave his family. His encounter with James, as much as he could talk with him before the latter fell asleep, made him realize he didn't want to be the Sirius his family wanted him to be. Away from his family, he could at last be himself. He wasn't obliged to behave like his parents told him to, always wanting him to be the good son of the great Black family and stay faithful to the Pure Blood…maybe he could even make friends with Muggles again, if there were some in Hogwarts. He missed his Muggle friends back at 12, Grimmauld Place.

Feeling suddenly tired after all this hard-thinking and the reassuring conclusion that he was free at last, Sirius put his legs on his seat and fell asleep, in a strikingly identical position as the boy who shared his compartment, James Potter.

AN: How do you find it ? I think it's not very well-balanced, I mean, lots of talk in the first half and lots of thinking/narrative in the last part. But that's the very first story I write about Sirius, in English, and the very first I publish so...
