Sirius' day had been a tough one. Dodging in and out of the common room, trying to avoid the bloodthirsty shroud of fanthings that follow his every move. His classes were mediocre today, the only interesting class today was Transfiguration where they had discussed animagi in depth. James, Peter and he had been excellingly good at the topic and the other students began asking if they were interested in becoming animagi once older. Smirking they all replied the same thing, "You could say that." He had also brought a new girl to his room, whom was scared away by the marks on his bedpost -- the number of girls whom had sat on his bed.
After the day of exhaustion, Sirius needed a place to relax, record his feelings in his journal. He couldn't do it in his room, James was probably lurking around somewhere with his invisibility cloak and would sneak in a read the entry without Sirius knowing. It seemed that the only place he could relax was the owlery. And only occasionally too, because James could always find him using the Marauders Map.
As Sirius walked up the stairs, his shoes clacked on the stone below him. His cloaks billowed behind him like the wings of a large bat, flapping in the wind. Rounding the corner to the owelry, he looked over the ledge and spotted a small black speck in the distance, flying unsteadily towards him. He continued the rest of the way up quickly and stood next to the window. As the animal came into view, it was a raven, black as coal. It cawed into Sirius' ear as it landed on his shoulder. Dropping a small piece of parchment in Sirius' hand, it flew to the place where all of the other owls were residing. Opening the note, Sirius read it carefully.
Dear Sirius,
You are not welcomed home for Christmas the holidays.
-Mum and Dad
Filled with a burning temper, Sirius angrily set the note on the ledge in from of him and set it on fire with his wand. Turning on it, he beckoned his raven to follow as he went and sat on the cold, stone floor.
