Selena prevented herself from rolling her eyes. She knew how to chop things up. That was what they did in potions. She placed the vegetable in one hand, the knife in the other. She set down the vegetable and sliced it neatly. 'Chop, chop, chop' Selena said with an oddly happy tune in her head. She was so weird at times. She was not going to chop off her fingers or hands. No matter what.
