Hmm. Let's see.
Dear Journal, This afternoon, I had my potions class with the first-year Slytherins and Gryffindors. That wretched Longbottom blew up his cauldron and when I was expressing my displeasure, the cowering idiot had an incident of accidental magic which turned my hair pink. Would Albus know if I Obliviated an entire class?
Dear Journal, When I find out who introduced Albus to Muggle bubble gum, his guts will be potions ingredients.
On a side note, my brother is a teacher. He says if he has one of those silent incidents where something ... slips out, the students always blame one of the other kids. After all, teachers wouldn't let one in class.
Author's Response: Thank you for your imput bridgeportfox. I especially love that bubble gum idea
and LOL. That last comment made me think of a joke i heard from a comedian once. That when he got annoyed with a kid, he would just quietly walk past their desk and let go a little fart
