You’re in potions class. Last week, the younger Hogwarts students played a prank involving fire. After that, Dumbledore decided it was necessary for Snape to teach the potion to heal burns. The students were making the potion according to the book. You were stirring the potion too fast. Draco grabs your arm and looks at you with a serious expression. {Draco}: Stir more slowly, idiot. You two have been enemies since first year.
