His Best Man

Chapter One

James and I have been best friends since we were kids.

As members of pureblood families, we were both required to attend various Ministry functions with our parents. That's where we met, when we were both six years old.

Flashback

"Just stay here, Sirius." His mother told him firmly, indicating his seat at their table. "Your father and I will be back once this song is done. Don't you dare go wandering off. If you get bored, you can talk to Bellatrix or Narcissa."

Once Mrs. Black's back was turned, Sirius rolled his eyes. He glanced at his cousins. Cissy was sitting there like the good little pureblood her parents wanted her to be. Bella's eyes were transfixed on the dance floor which her parents, as well as his, had just disappeared on to.

After sitting there, slouched over with his chin resting on his hand, Sirius spotted someone else doing the exact same thing a few tables over. It was a boy who looked to be about his own age, with untidy black hair and glasses, looking just as bored as Sirius felt. With a last glance at his two cousins, Sirius got up and walked over to the other boy.

"Hello." Sirius said, standing right in front of the boy.

The other boy's head jerked up at the sound of Sirius's voice. "Oh, hello." He replied.

"Watcha doin'?" Sirius asked, taking the empty seat next to the boy. In fact, all of the chairs at the table were empty. The black-haired boy was sitting there all by himself.

"I was looking for my parents." The boy said, nodding in the direction of the dance floor. "But I lost them ages ago."

"That's boring." Sirius said. "Let's do something fun."

"OK." The boy agreed, eagerly sitting up. "I'm James, by the way. James Potter. Who are you?"

"Sirius Black." Sirius replied. "Wanna play a prank on my cousins?"

"Yeah." James said, an evil glint appearing in his eye. "What do you have in mind?"

An identical look appeared in Sirius' eye. "Well…"

"Ahh!" Came the shout a little while later, from the table where Narcissa and Bellatrix were no longer sitting..

"Mission accomplished." James said as he gave Sirius a high five.

"Huh?" Sirius said, a clueless expression on his face.

James shrugged. "Mum says it all the time."

"Speaking of your mum…" A voice said from behind the two boys, who had retaken their seats at James' table.

"Uh-oh." James said, as he turned around to find his parents standing there.

"So tell us James, did you have anything to do with the spiders at the Black's table?" His mother asked.

James nodded slowly.

"It was my idea." Sirius said quickly, cutting Mr. Potter off as he was about to say something. "I asked him to do it."

"But I found all the spiders." James said, turning back to Sirius. "It was my idea to use them. You just said we should prank your cousins."

"You're a Black?" Mrs. Potter said, looking at Sirius with interest.

Sirius nodded his head slowly.

"The Black heir?" She clarified.

Again, Sirius nodded.

"I used to be a Black." Mrs. Potter said reminiscently, sitting in the chair next to Sirius. "Dorea Black. I'm your mother's aunt."

End Flashback

Somehow, James and I never got in trouble for pulling that first of many pranks on my cousins. His mum was too distracted by the fact that we were all related, and his dad didn't seem to care about the prank at all. Looking back, now, I think he was about to congratulate us before I interrupted him. I always knew there was a reason I liked Mr. Potter.

It was at that Ministry banquet, when we pulled our first prank together, that James and I first became friends, and never, for one moment, have either of us ever regretted it.

We've been best friends through thick and thin. We've stuck by each other's side through it all. That's how I got where I am today…standing next to James at his wedding, as his best man.
