Harry took the water and sipped it carefully shaking his head, "No, I think that had more to do with the thought of flying. Merlin, it's been so long."
"It's kind of like building immunity, I have to be careful around you, but not like before, now it is more about my personality, like flying and making fun of Voldemort at lunch."
He finished the water. "They're trying to break me, but it can't be any worse then the Durselys trying to stomp magic out of me for 11 years by locking me in a cupboard or using me as a punching bag."
"At least you care that I'm sick and make me feel better," he gave a self disparaging smile.
And he wouldn't stop fighting. They obviously didn't know him very well.
