"Yes," Luna agreed with Harry's observation, nodding slightly. "It makes sense. They always want you to eat or drink something at the Ministry check-ins. And those are the only days I feel tired anymore. I think back at Hogwarts they were giving it to us most days. It's either that or I wasn't used to it yet."
She smiled slightly at Ron, shaking her head. "No, thank you. I think I've already digested the rest; there's nothing left to get rid of." She yawned again, covering her mouth as she forced herself to sit up straight. "I am terribly tired, though," she admitted.
