12th November 1971

Potter has been making a habit of annoying the Slytherins. He's been tripping them up in the corridors and jinxing them. He attacked Severus today – it's happening all the time now. He keeps calling him Snivellus. I tried to stop him but Potter just called him Slytherin scum. I told him that he's just like the Slytherins but he told me he'd never hurt a muggle. But neither would Severus. I know Sev. He's my best friend. He'd never do that.

I've been given tons of house points. I think Professor Slughorn gives me the most. I am very good at potions though.
