"Excuse me," Luna tapped Draco on the shoulder, "May I borrow your soul?"
Draco stared straight ahead, his resolve steely. He had endured sitting next to Luna in their shared Astrology class for the majority of the year, and was not about to let her shatter his perfect calm. Luna stared at him expectantly for a solid five minutes. Draco didn't even notice, because he Didn't Care.
Luna raised her hand, "Professor," she called, "Draco's gone into some sort of trance."
"Shut up," Draco snarled. Sweetly.
"Mr. Malfoy appears to be in control of his facilities," the professor noted, in a tone of extreme boredom, before resuming her lecture. She was very used to their little routine by this point.
Luna looked back around at him, "Oh. Sorry, Draco. I thought perhaps you were communicating with aliens and grew concerned for your safety."
"There's no such thing as aliens!" Draco snapped, before he was able to control himself. He regretted his decision immediately as Luna once again turned on him with her enormous, round eyes.
"Are you certain, Draco? Did the aliens tell you that?" she inquired in a tone of only the politest interest. Draco ground his teeth.
"Aliens are a silly thing made up by stupid Muggles who don't understand the complexities of the night sky," he scoffed, raising his voice slightly so his professor would hear. She kept her back to him, scrawling lazy notes over the blackboard.
"Ten points from Slytherin for lacking subtlety and a sense of shame," she droned. Draco pursed his lips. Luna patted him sympathetically on the shoulder.
