3. Scatter rose-petals in front of him wherever he goes.
The following day, Snape was feeling particularly nasty in class, he assigned at least five detentions and deducted over fifty points. As the bell rang out, everyone dashed out of the classroom but I stayed behind. I transfigured an old book into a basket of petals and proceeded to scatter them on his desk. He looked up suddenly, he glared at me before picking up a petal between two fingers and dropping it to the floor. ''What are you still doing here?'' He asked, voice dripping with venom. ''I thought class was over.'' He added sarcastically. When I purposely didn't reply he stood up and pointed to the door angrily, ''Get out!''
I turned the basket upside down, emptying it of its contents, the petal and smiled sweetly at him. ''As you wish, professor.'' I said quietly as I hurriedly closed the door behind me, chuckling inwardly. Now he'd have to clean that up, not that I cared he deserved it really.
