You and Fred hated each other. He was a Gryffindoor, and you were a Slytherin.

One day, you two were bickering, as usual, and you were eating a sweet.

Fred:"Sly Gryffindoor," ( I said, gesturing to myself)

Fred:"Dumb Slytherin," (I gestured to you.)

You:"I'm not a dumb Slytherin," (you growled back.)

Fred:(smirking)"Right, and you're not eating a p##ing pasty."

I felt so smug when Ilaria's eyes widened. Yet another one of my pranks was a success.
