Watching the new students arrive is always an unpleasant experience for me.

Watching them trembling as they wait to be sorted and gleaming when they get put into the house they hoped for.

However there is always one who gets parted from a friend, always one who gets placed in the wrong house for them, always one whose heart is torn in two as they walk the opposite way to someone they love.

Just like I did.

It brings back terrible memories of her, of Lily, the gleam of happiness brought to her face as the hat shouted Gryffindor, and the empty disappointment and realisation as I walk the opposite way into the sea of green.

That's what parted us- that one decision made by a sodding hat tore us apart forever.

I fight back against the lump in my throat as I write this.

I hope she thinks of me, wherever she is.

Albus came down to my office about an hour ago warning me against the dementors. The minister has tried to insist we have them inside the castle; however Albus put a quick stop to that idea. They have been limited to the boundaries of the grounds, with strict instruction not to enter. I am glad; I hate them as much as Albus.

I have spent the afternoon planning lessons for my classes tomorrow; I have double third years, Slytherin and Gryffindor and a sixth year class in the afternoon. That means I spend the morning making sure Potter looks a fool in front of everyone and just certifying that he knows how much I hate him.

Albus is past trying to make me see reason, and I know I never shall. Every time I look at him I see his arrogant jerk of a father. Unless I look into his eyes of course… her eyes.

I must venture to Dagon Alley tomorrow evening as I am running low on my bat wing stock. I doubt I shall have time to write in my diary and will be very tired after a busy day, but I shall try to update you as soon as I can.
