Sitting cross-legged on her bed, Audrey frowned at her textbook. She understood the concept behind non-verbal spells but was having serious trouble with the execution. No matter how hard she tried, she just couldn't make them work. She heaved a sigh and tucked her hair back behind her ears. Maybe she just wasn't concentrating hard enough.
She took a deep breath and closed her eyes, trying to centre herself and clear her mind. Eyes still squeezed shut she raised her wand and pictured the piece of paper sitting on her bed. Wingardium leviosa! She thought, as hard as she could, moving her wand and opening her eyes.
The paper had moved! Audrey let out a happy gasp, then realised the curtains surrounding her bed were now open. It hadn't been her magic, but air currents caused her best friend, who had moved the paper.
"Hey, Evie," she murmured, dejectedly, putting her books and papers together to make room for the other girl to slide onto the bed.
