It happened the next morning at breakfast. Sirius was just pouring some milk onto his cereal when a large, impressive owl landed haughtily in front of him. It dropped a crimson envelope onto his plate and flew off.

"Oh no." Sirius's hand started to tremble as he reached out for the letter. He looked to his friends for guidance but they simply told him to open it and get it over and done with. He nodded, took a deep breath and opened it.

It happened instantly. As though an explosion had erupted, the letter started screaming with his father's voice.

"SIRIUS BLACK! I AM SO DISGUSTED WITH YOU! WHY DID YOU LIE TO ME? YOU DIDN'T SERIOUSLY THINK YOU'D GET AWAY WITH IT DID YOU? GRYFFINDOR? GRYFFINDOR? I HAVE NEVER BEEN SO DISSAPOINTED IN MY OWN FLESH AND BLOOD! YOU ARE NO SON OF MINE!" It carried on much the same for a few moments, then the envelope curled up and burned to ashes.

"What are looking at?" James shouted angrily at some Ravenclaws who were passing their table. To his surprise Sirius was grinning. "What on earth is so funny?"

Sirius roared with laughter, tears were streaming down his face. "Didn't you hear what he said?"

"That you were a disappointment and he doesn't want anything to do you ever again? Dead funny yeah." James looked at his friend as though he was mad. Lily Evans, who was sat next to Sirius, moved as far away from him as was possible, a look of fear on her face.

"He thinks it's a punishment. He thinks I care that he is my father. But I don't. It's a blessing, not a punishment!" James looked at Sirius like he was mental for a minute. He couldn't quite understand Sirius most of the time, but not wanting the love of his father? James had never exactly liked Mr Black, but he couldn't imagine what he had done to cause so much hatred in his own son.

"Hi guys," Remus appeared at the table, looking tired and thin. "What have I missed?"

Sirius was in an extremely good mood for the rest of the day. He persuaded the other boys to forget their History of Magic homework and go outside as it was a nice day. There were a lot of students making the most of the pleasant March weather walking around the lake. James tripped over his cloak when he saw Lily and landed in a pile of mud.

"Nice howler Black," drawled a voice from behind the group. They spun around to see Severus Snape looking undeniably vindictive.

"Liked it did you?" James spat.

"Yeah did we give you something to laugh at other than your own reflection?" Sirius narrowed his eyes and looked straight at the boy he hated. All three boys drew their wands at once.

"Please don't James, Sirius!" Lily shouted from next to Remus.

"Shut up you nasty little mudblood!" Snape hissed at her.

"That's it!" James roared. He whipped his wand and sent Snape flying into the same pile of mud he himself had fallen into.

Snape pulled himself up and pointed his wand at James, muttering something under his breath. James immediately started burping. Every time he did, a bit of blue slime slithered out his mouth and crept over his skin like a rash. Sirius turned to see what was causing his friend to retch. As he did, Snape hit him from behind with a curse which sent him into a full body lock. The last thing he remembered, with some gratification, before he hit the ground, was Professor Dumbledore's voice shouting "Detention Snape and 50 points from Slytherin!"
